Cookie Run: Braverse Extra Deck Guide — All 23 Cards

Here is a bet I will take every time: pull six random Braverse players off a locals table, look at their Extra Decks, and at least four are running an EXTRA card whose condition their deck cannot reliably meet. Not because they misread it — because they read "LV.3, six HP, hits for 3" and stopped. The stat line is the least interesting thing on an EXTRA card. The condition is the card.

The Extra Deck is the only zone in Braverse that costs you nothing. Your main deck is a hard 60 and every slot is a fight; the Extra Deck is up to six cards sitting outside that 60, doing nothing to your consistency. Free power. And the pool is small enough — 23 unique cards, every one an Ultra Rare — that there is no excuse for guessing. Every card, condition, and stat below is quoted from the official card database.

Six slots most players fill on vibes

The failure mode is always the same. A player opens a Shadow Milk Cookie, thinks "that's the best card I own," and slots it. Then it sits there for eleven rounds because the Purple one (BS9-102) needs 20 cards or more in each player's trash, and their deck is a Red aggro list that wins on turn six with nine cards in the bin.

That is not a bad card. That is a card in the wrong deck. An EXTRA whose condition never fires is worse than a blank — it convinced you that you had a late-game plan.

The right mental model: an EXTRA is a payoff for a game state your deck is already trying to reach. Read the condition first. Ask "does my deck do this on purpose, by turn five, in a game I am not already losing?" If no, the card is not for you no matter what it costs.

What the Extra Deck actually is

The Extra Deck is an in-game zone, not a sideboard. That is the single most common misconception in Braverse discussion, so: it is up to six cards living beside your main 60 for the entire match. You do not swap them between games — there is no swapping in Braverse at all, since decks are registered and locked before the event. The Extra Deck is registered too, and it is the same six cards in game one and game three.

What makes the zone work is that EXTRA cards do not get played the normal way. They ignore the cost-and-level progression from the turn structure guide. Instead, each carries an 【EXTRA】 clause describing a board state, and when your board matches, the card comes down. No energy ramp to LV.3, no Awaken chain in most cases — just the condition. That is why the zone is powerful and so easy to waste: it is six cards of "if my game goes the way I planned, I get a free bomb," and the planning is on you.

Note also that the official database filters list EXTRA as its own type, alongside COOKIE, ITEM, TRAP, and STAGE (plus FLIP), but the Comprehensive Rules (Ver. 1.8) still treat any card with a Level and HP as a Cookie card, and refer to these as "EXTRA Cookie cards." Once one is in your battle area it is a Cookie like any other.

The whole pool is 23 cards

Here is the part that should change how you approach the zone: the entire EXTRA pool on sale is 23 unique cards. Not 23 good ones — 23 total, out of 2,311 entries in the English database as of October 26, 2026. Alternate printings (SUR and EXR arts, one GXR, and a handful of promos) pad that to 60 database entries, but they collapse to 23: four each in Red, Yellow, Green, Blue, and Purple, plus one Pure and two Black.

The database also lists a 24th, a Blue Shadow Milk Cookie (ST11-015) for the Timeline of Fate starter deck. The official product listing gives that deck no release date yet, so it is left out of the count and the card list below.

Every single one is an Ultra Rare — no commons, no uncommons, no budget line. That makes the Extra Deck the most expensive six cards in your bag, and worth getting right on paper before you buy anything.

The other structural fact: EXTRA cards did not exist before BS8. Sets BS1 through BS7 contain zero. The type debuted with Land of Fire & Ruin, Realm of Apathy (BS8), which shipped five; BS9 and BS10 added five each, The Dark Enchantress War (BS11) added two, and Festival Arena (BS12, released October 2, 2026) added six, one each in Red, Yellow, Green, Blue, Purple, and Black. If you built out of the early sets and wondered why you never saw the zone used, that is why.

The three kinds of EXTRA condition

Line them all up and the conditions sort into three buckets. Knowing which bucket you are shopping in saves you from the vibes problem.

Attrition conditions: you had a bad turn

These fire off your own Cookies dying — Avatar of Ruin (BS8-005) at 2 or more of your Cookies fainted this turn, the Red Shadow Milk Cookie (BS9-010) at 2 or more of your Red LV.1 Cookies fainted during your opponent's previous turn. They reward you for getting blown out. That is a real design idea, and it is why aggro decks that flood LV.1 bodies get the best deal in the zone: they trade constantly, so the condition is nearly free.

Resource conditions: you hoarded or dumped

These read your hand, trash, or support area, and they cut both ways. Jagae Cookie (BS10-098) wants 7 cards or more in hand; Will of Nature (BS8-090) wants 2 cards or less. Same color, opposite tells — a nice little tax on greed, since you cannot use both well in one deck. Peak of Apathy (BS8-069) reads the board sideways, unlocking when your support area has 2 or more cards less than your opponent's: the only EXTRA that turns being behind on resources into a resource. Festival Arena's six mostly land here too: five of them check a break area or a support area.

Awaken conditions: you built the Cookie first

The third bucket is the demanding one. These do not create a body — they upgrade one, stacking onto an existing Cookie via 【Awaken】. You can spot them by their HP, printed as a plus value instead of an absolute: Pure Vanilla (BS9-088) at +0; Hollyberry (BS10-024) and White Lily (BS10-073) at +1; Golden Cheese (BS8-027), Dark Cacao (BS8-104), and Dark Enchantress (BS11-116) at +2. Highest ceiling in the pool, and only for decks built around a named Cookie from the ground up.

Card by card: every EXTRA in the game

Levels, HP, and conditions below are as printed on the card images in the official database.

Red

• Avatar of Ruin (BS8-005) — LV.3, 5 HP. Playable if 2+ of your Cookies fainted this turn. On Play: all of your opponent's Cookies receive 1 damage. Power of the Destroyer hits for 3, then all other Cookies receive 1. The most deck-agnostic EXTRA in Red.
• Shadow Milk Cookie (BS9-010) — LV.2, 4 HP. Playable if 2+ of your Red LV.1 Cookies fainted during your opponent's previous turn. On Play: add a card from your opponent's hand face-up to the bottom of this Cookie's HP. It eats their hand and turns it into your life total.
• Hollyberry Cookie (BS10-024) — LV.3, +1 HP, Ancient. Discard 1 card to Awaken your Hollyberry Cookie that has 3 or less HP remaining. On Play: until the end of your opponent's next turn, it takes 1 less from all damage. Shield of Conviction hits for 2, and two more Red energy deal 2 to one of your opponent's Cookies. Hollyberry decks only. (Read the card image, not the database's text field: that field shows the can't-attack skill of the LV.2 Hollyberry, BS10-021, which this card does not carry.)
• Shining Glitter Cookie (BS12-018) — LV.2, 5 HP. Playable if your break area is LV.4 or higher, by discarding 1 Arena card from your hand. Once per turn, it can set another Red Arena Cookie in your battle area as active. Beauty Check! hits for 4, plus 1 damage to an opponent's Cookie if you started the game going second.

Yellow

• Golden Cheese Cookie (BS8-027) — LV.3, +2 HP, Ancient. Awakens a Golden Cheese Cookie played from your break area this turn. Also self-recurs: from the break area it can trash itself to move a Golden Cheese Cookie from your trash back to the break area.
• Shadow Milk Cookie (BS9-030) — LV.3, 6 HP. Costs discarding 3 Yellow Cookies that have FLIP from your hand — a brutal price that only pencils out in a dedicated FLIP shell. Its attack discards a FLIP Cookie to fire that card's FLIP effect, which is the real value.
• Warden of the Heart (BS10-048) — LV.3, 6 HP. Needs your break area at LV.5+ and any of your Cookies to have gained HP this turn. No named Cookie, keyword, or discard required, which makes it the gentlest Yellow condition.
• Clotted Cream Cookie (BS12-036) — LV.2, 4 HP. Playable if your break area holds 4 or more Yellow Arena Cookies. On Play: +2 HP if you started the game going second. aka. Genius Idol hits for 3, then lets you place another Arena Cookie from your battle area into your break area to play a LV.1 Arena Cookie with a different card number.

Green

• Peak of Apathy (BS8-069) — LV.2, 4 HP. On Play: place a Green card from your trash into your support area as active — it pays back the exact resource whose absence unlocked it.
• Shadow Milk Cookie (BS9-055) — LV.3, 5 HP. Needs 3+ cards in your opponent's support area and 2+ cards moved from your support area to your trash this turn.
• White Lily Cookie (BS10-073) — LV.3, +1 HP, Ancient. Awakens your White Lily Cookie when your support area has 8 or more cards. Dawn Lily Protection hits for 4 off four Green energy, then lets you return a Cookie from your support area to your hand to place the top card of your deck into your support area as rested. (Same database slip as Hollyberry: the text field shows the On Play of the LV.2 White Lily, BS10-069. The printed card has no On Play.)
• Apple Faerie Cookie (BS12-056) — LV.2, 3 HP. Playable if you have a Candy Apple Cookie with Arena in your battle area, or 7 or more Green cards in your support area. Faerie Song hits for 2; if you started the game going second, you can then discard 1 card to set a card in your support area as active.

Blue

• Will of Nature (BS8-090) — LV.3, 5 HP. Playable at 2 or less cards in hand; attack draws up to 2. The empty-hand comeback card.
• Pure Vanilla Cookie (BS9-088) — LV.3, +0 HP, Ancient. Yes, plus zero, printed in the same +HP slot as the other Awaken cards. Awakens a Pure Vanilla Cookie if a Cookie went from your battle area to the bottom of your deck this turn, and its On Play can hand it +2 HP by revealing a Blue LV.2 Cookie off the top.
• Jagae Cookie (BS10-098) — LV.3, 6 HP. 7+ cards in hand, discard 2 Blue. Then it pumps a Cookie's damage once per turn for a discard. The Blue draw-engine payoff.
• Popping Candy Cookie (BS12-074) — LV.3, 5 HP. Playable if an Arena Cookie went from your battle area to the bottom of your deck this turn. On Play: draw up to 2 if you started the game going second. Fan Service hits for 3, then reveals the bottom card of your deck: if it is a LV.2 Arena Cookie, you add it to your hand and put the top HP card of one opponent's Cookie on the bottom of their deck.

Purple

• Dark Cacao Cookie (BS8-104) — LV.3, +2 HP, Ancient. Awakens a Dark Cacao Cookie played from your trash this turn. Dragon Lord's Judgment hits for 4 and strips a card off an opponent Cookie's HP.
• Shadow Milk Cookie (BS9-102) — LV.3, 6 HP. The 20-cards-in-each-trash card. Only for mill and grind decks, full stop.
• Spectral Warmaster (BS10-123) — LV.3, 4 HP. Playable if you refreshed during this game, discard 2. Its attack hits for 3 then trashes itself — a one-shot haymaker for decks that mill themselves out.
• Black Lemonade Cookie (BS12-092) — LV.3, 5 HP. Needs 3 or more Arena Cookies with Blocker in your break area, and you place a Purple LV.2-or-lower Cookie from your battle area into your trash to play it. Whenever one of your Cookies faints while your opponent holds 3 or more cards, they put a card from their hand into their trash. Flying Pick hits for 4, with one more discard for them if you started the game going second.

Pure and Black

Three cards: the only Pure EXTRA and the only LV.5 EXTRA, both from BS11, plus Festival Arena's Black addition.

Avatar of Destiny (BS11-091) is the only Pure EXTRA: LV.3, 5 HP, playable when both players' break areas are LV.6 or higher and both players have 3 cards or less in hand. That is a symmetric condition — it does not care whose deck it is in, and only fires in a genuine topdeck war. When it does, Destiny: Punishment hits for 5 off four generic energy.

Dark Enchantress Cookie (BS11-116) was the first Black EXTRA and is still the only LV.5 card in the pool. It needs your break area at LV.7 or higher and [Dark Enchantress's Castle] (BS11-108) in your stage area, and it Awakens your LV.3 Dark Enchantress Cookie (BS11-115) that has Special Play. Fornacem Accende! hits for 7 — the biggest attack number in the zone — and the Cookie cannot be moved from the battle area by your opponent's effects. Three build requirements for the game's largest body. That is the correct price.

Poison Mushroom Cookie (BS12-111) is the second Black EXTRA: LV.3, 5 HP, playable when your opponent's support area has 4 or more cards and you have a Cookie with Special Play in your battle area. While it is out, your other Black Arena Cookies in the battle area gain +1 attack damage. Eat This Please hits for 2, and the Cookie gains +1 HP if you started the game going second. It is also the only EXTRA with a Genesis Extra Rare printing (BS12-111@3).

How to actually fill your six

The rule I would tattoo on a playmat: an EXTRA card earns its slot if your deck meets its condition in a game you are winning or drawing, not only in games you are already losing.

That kills a lot of tempting slots. Avatar of Destiny needs both hands down to 3 cards or less and both break areas at LV.6+ — but for an aggro deck, reaching that state means your plan already failed. It is not a comeback card for you. It is a card for control decks that want the long game.

• Match your archetype, then your color. Aggro takes attrition (Avatar of Ruin, Red Shadow Milk). Control takes resources (Will of Nature, Jagae, Avatar of Destiny). Combo takes Awaken (Golden Cheese, Dark Cacao, Dark Enchantress).
• Do not run all six as different cards. Duplicates are legal and the zone has no consistency cost — if Avatar of Ruin is your best line, run two.
• Zero is a real answer. On a two-color midrange list with no named-Cookie theme, several conditions are genuinely unreachable. Two live cards beat two live cards plus four blanks.
• Awaken cards are a deck commitment, not a slot. Dark Enchantress Cookie requires BS11-115, BS11-108, and a Black shell reaching a LV.7 break area. That is not an Extra Deck decision — it is the whole deck.

The mistakes that waste the zone

1. Slotting the expensive one. The SUR and EXR arts are the same card. Price signals collectibility, not condition reachability. A chase-price Shadow Milk in an aggro deck is still a blank.
2. Running Jagae and Will of Nature together. Opposite hand-size conditions in the same color — one is always dead. I have watched this exact list at three different tables.
3. Forgetting it is not a sideboard. You cannot fix a bad Extra Deck in game two. Same six every match, since the tournament list is locked.
4. Treating the +HP cards as bodies. They upgrade a Cookie already on board. If the base Cookie is dead, so is your EXTRA.

The zone is free, but only if you earn it on the build sheet. Six cards, 23 to choose from, and the only question that matters is whether your deck reaches the condition on purpose.

Quick Action Checklist

• Up to six cards, outside your main 60, registered with your list and locked for the event. Not a sideboard.
• The whole pool on sale is 23 unique Ultra Rares: 4 each in Red/Yellow/Green/Blue/Purple, plus 1 Pure and 2 Black. None printed before BS8.
• Read the 【EXTRA】 condition before the stat line. If your deck does not reach that board state on purpose by mid-game, the card is a blank.
• Aggro plays attrition: Avatar of Ruin (BS8-005), Shadow Milk Cookie (BS9-010). Control plays resources: Will of Nature (BS8-090), Jagae Cookie (BS10-098), Avatar of Destiny (BS11-091).
• Never run Jagae Cookie and Will of Nature together — their hand-size conditions are direct opposites.
• Any EXTRA with a +HP value is an Awaken upgrade needing its base Cookie already on board.
• Run duplicates freely, and run fewer than six without guilt. Live cards beat filler.
