How the deck wins

The list is 26 Hakui Koyori plus 2 AI Koyori (28 holomem) with Robocosan as the oshi and 20 White Cheer. There is no Robocosan holomem, so the oshi skill I'm Not Broken!! can never be used and the SP skill (1 holo power) is a once-a-game draw 2, archive 2.

The engine is the #KOYO LABO support: 4 Solved with a Bang! (tool, Arts+10) and 1 Koyori's Assistants (fan). 1st hBP04-012's bloom and debut hEB01-019's collab (going second, on your first turn) search them, and 2nd hBP04-013's Koyori's Awakening finds another whenever a #KOYO LABO card is attached to it.

2nd hBP04-013 (200 HP) is the main attacker at 160 (+50 against green); 2nd hBP06-021 (190 HP) gives a #holoX holomem Arts+30 when it collabs (+50 if a #KOYO LABO support is attached to hBP06-021 itself) and hits for 90, +40 if it puts a #KOYO LABO card from your archive on the bottom of your deck.

Summer Concert gives your #Summer Koyori (the hEB01 debuts and 1sts) Arts+30 and sends a cheer from the archive; Manager-chan and Borderline Evil Robot refill the hand.

Key cards

2nd Koyori hBP04-013 (main attacker)

Koyori's Awakening, white + 2 colorless: 160 (+50 against green); if a support card with #KOYO LABO is attached to this holomem, reveal 1 #KOYO LABO support from your deck and add it to your hand. Gift I'll Never Give Up!: when it downs an opponent's holomem, put the top card of your deck into holo power, then add 1 card from your holo power to your hand. 200 HP.

Attach Solved with a Bang! to it and attack every turn.

2nd Koyori hBP06-021

Collab Reaching Out to You: choose 1 holomem with #holoX on your stage; this turn it gets Arts+30, or +50 if a #KOYO LABO support is attached to this holomem. Page from Our Youth, white + colorless: 90 (+50 against red); you may return 1 #KOYO LABO support from your archive to the bottom of your deck for +40. 190 HP.

A collab booster for the center hBP04-013, or a cheap second attacker.

Solved with a Bang! (#KOYO LABO tool)

Arts+10. On a 2nd Hakui Koyori in the center or collab position: at the end of your performance phase you may archive it to deal 30 special damage to the opponent's center holomem. Only 1 tool per holomem.

Turns on Koyori's Awakening's search; archive it for 30 special damage to finish a holomem.

1st Koyori hBP04-012

Bloom Yes! Yes! Yes! Yes!: reveal 1 #KOYO LABO support from your deck and add it to your hand. Koyo and Her Assistants Will Always Be Together!, 1 white: 30; draw 1 if Koyori's Assistants is attached. 140 HP.

Bloom it to find Solved with a Bang!.

1st Koyori hEB01-020

I Chose This Yukata After Studying My Assistant's Tastes♡, 1 colorless: 30. Let the Exciting Experiments Begin!, yellow + colorless: 50, +10 for each holomem among the top cards of your deck equal to your cheers. 190 HP. #Summer.

The sturdy 1st; with only white cheers it attacks with its 30.

Summer Concert

LIMITED event: this turn all holomem with #Summer on your stage get Arts+30. Send 1 cheer from your archive to your holomem.

Extra damage for the hEB01 Koyori and a cheer back from the archive.

The list has no Robocosan holomem, so I'm Not Broken!! can never be used and the SP skill attaches nothing (no Roboser). Koyori's Awakening searches only if a #KOYO LABO support is attached to the attacker. Solved with a Bang!'s 30 special damage works only on a 2nd Hakui Koyori in the center or collab position. 1st hEB01-020's second Arts needs yellow, and this list has only white cheers. Summer Concert boosts only #Summer holomem (the hEB01 Koyori), not the 2nds. Yamada Lui the 54th needs every holomem on your stage to have #holoX. Borderline Evil Robot makes both players reshuffle and draw 4 once your life is 3 or less.

Game plan

Turns 1–2

Early game

Fill the stage and find #KOYO LABO cards.

  1. Normal PC places a Debut from your deck; Yamada Lui the 54th (LIMITED; only if every holomem on your stage has #holoX) adds 2 #holoX holomem.
  2. Going second on your first turn, collab debut hEB01-019 to add a Debut and a #KOYO LABO support from your deck; debut hSD06-008's collab draws 1 with a #holoX center and 5 or fewer cards in hand.
  3. Bloom 1st hBP04-012 to search a #KOYO LABO support, or 1st hEB01-020 for a 190-HP body.
Turns 3–4

Mid game

Get 2nd hBP04-013 into the center by turn 3 or 4.

  1. Bloom 2nd hBP04-013 in the center and attach Solved with a Bang! (Arts+10) so Koyori's Awakening searches another #KOYO LABO card each attack.
  2. Koyori's Assistants can only go on a Hakui Koyori and may move 1 cheer from your stage to it when attached from hand or archive.
  3. Manager-chan (draw 5) and Borderline Evil Robot (draw 4) reset the hand; both are LIMITED, so only one a turn.
Turn 5 on

Late game

Attack with Koyori's Awakening.

  1. Attack with 2nd hBP04-013 for white + 2 colorless every turn; when it downs a holomem, I'll Never Give Up! adds a card from holo power to your hand.
  2. Collab 2nd hBP06-021 for Arts+30 on the attacker (+50 if a #KOYO LABO support is attached to hBP06-021 itself); Summer Concert adds Arts+30 to the #Summer Koyori instead.
  3. Archive Solved with a Bang! from a 2nd Koyori in the center or collab position at the end of the performance phase for 30 special damage to the opponent's center.
  4. The trained AI wins in about 9 of its own turns.

Practice it

  1. In Match Lab's Player vs Bot, play against the Roboco-oshi Koyori Loop (JP) Specialist AI first and watch how it sets up.
  2. Then pilot the deck yourself: get Solved with a Bang! onto a center 2nd hBP04-013 and let Koyori's Awakening keep finding #KOYO LABO cards.
  3. Aim to win in about 9 of your own turns, like the trained AI does.
