How the deck wins

Every holomem is Moona, so IDENTIFY -AREA 15- always works and the #ID Gen 1 searches never miss.

Once per turn, for 1 power, Kobo's Rain Shamanism deals 20 special damage when a blue holomem's ability archives a cheer. 2nd Moona hBP08-054 archives 3 cheers to draw 3, which also fires Kobo's skill.

2nd Moona hBP06-053 adds 90 special damage with 4+ cheers, and her collab deals damage equal to what the target has already taken. Kobo's 6 life gives you time to set it up.

Key cards

2nd Moona hBP08-054 (main attacker)

You're Not Alone, We're Together Now: 130 for 3 colorless; may archive 3 cheers to draw 3. Bloom: send blue cheers from the archive to 1-3 Gen 1 holomem.

Your best attacker; the trained AI uses it far more than the general AI.

2nd Moona hBP06-053

Tidal Eclipse: 90, plus 90 special damage to their center or collab with 4+ cheers. Collab: special damage equal to the damage the target has taken.

Second finisher. Load it with 4 cheers first.

Kobo Kanaeru (oshi)

1 power: when your blue holomem's ability archives a cheer, 20 special damage. SP 3: send 1-5 archived cheers to #ID holomem.

Fire Rain Shamanism when hBP08-054 archives cheers. Save the SP; the trained AI uses it only when it really helps.

1st Moona hBP09-060

Bloom: look at the top 3 and take a Gen 1 holomem. Arts: 50 and 10 special to center and collab.

Your favorite first bloom; it digs for the 2nds.

1st Moona hBP01-090

Bloom: search a green or blue cheer and attach it.

Bloom it often for extra cheers.

IDENTIFY -AREA 15-

All-Gen 1 stage only: take 2 Gen 1 holomem from the deck.

Your main search card.
