How the deck wins

This is the EN-pool version of Myth Reunion, using only cards in the English card pool through Diva Fever (hBP07), including the hEB01 Summer set and the start decks through hSD19. The hBP08 Kiara Debut x2 becomes Kiara Debut hBP01-062 x2, the Myth event x3 becomes 1 more Archive PC and 2 more Harusaki Nodoka, and Creator PC x3 becomes Friendly PC x3 (Calliope Debut hBP02-054, Ina Debut hBP02-061 and Kiara Debut hBP01-062 can all be put out with it). The oshi is still Mori Calliope hBP02-007, with 31 holomem, 19 support cards and 20 Purple Cheer.

2nd Calliope hBP06-060 is the deck. Bull's-Eye!!!! does 60 for 1 colorless and, with Calliope as oshi, can archive the top 2 cards of your deck to send the top card of your cheer deck to your holomem. Memento Mori. does 200 for 4 colorless (both +50 against red), gives 1 #Myth holomem Arts+20 this turn, and draws 1 if your archive has 8 or more holomem.

Calliope's SP Reaper's Rap (2 holo power, [1/Game], only with a Calliope in the center) lets a Calliope use the same Arts once more this turn after she uses it. Two Memento Mori in one turn is 400 or more damage and ends most games. The other skill, Sampling (2 holo power, [1/Turn]), archives 2 cards from your hand to return 2 #EN holomem from your archive to your hand.

This run trained under JP rules on an EN-legal list (the server only accepts EN cards that have already been released in English; Diva Fever comes out in English on 2026-11-20). The trained AI started from the JP Myth Reunion AI and played 25,000 more games with this list. On the same deals it won 70.1% against the field, up from 65.4% for the JP AI piloting this list (the JP list scored 77.1%).

Key cards

2nd Calliope hBP06-060 (main attacker)

Arts Bull's-Eye!!!!: 60 for 1 colorless; with Calliope as oshi you may archive the top 2 cards of your deck to send the top card of your cheer deck to your holomem. Arts Memento Mori.: 200 for 4 colorless; 1 #Myth holomem gets Arts+20 this turn, then with Calliope as oshi and 8+ holomem in your archive, draw 1. Both +50 against red. 210 HP.

Your finisher; the trained AI deals almost all its damage with her.

Mori Calliope (oshi)

Sampling, 2 holo power, [1/Turn]: archive 2 cards from your hand to return 2 #EN holomem from your archive to your hand. SP Reaper's Rap, 2 holo power, [1/Game], only if your center is Calliope: this turn, after 1 of your Calliope uses an Arts, she uses the same Arts once more.

Save the SP for a double Memento Mori, around your 6th turn.

1st Calliope hBP06-059

Bloom Sleepover Parties!: if your stage has 3 or more #EN holomem, send a blue or purple cheer from your cheer deck to your holomem. Arts Half Asleep: 80 for 3 colorless. 160 HP.

Bloom it on your 2nd turn with 3+ holomem out; the trained AI does it in every game.

1st Calliope hBP06-058

Collab Yes, Chef.: draw 3 cards, then archive 2 from your hand. Arts A Chef's Journey's End.: 30 for 1 colorless; with a purple cheer attached, draw 1, then archive the top 2 cards of your deck. 160 HP.

Collab it to dig and to put holomem into the archive for Sampling.

SorAZ Celebration

LIMITED event. Draw 2 cards. Look at the top 5 cards of your deck, reveal 1 1st holomem and add it to your hand; the rest go to the bottom in any order.

Finds a 1st Calliope early.

Archive PC

LIMITED item. Return 1-3 holomem from your archive to your deck and shuffle it. Draw 2 cards.

Now 3 copies. It refills the deck, but it also takes holomem out of the archive that Sampling and Memento Mori's draw use.

The EN list is about 7 points weaker than the JP list (70.1% vs 77.1%) after losing the Myth event and Creator PC. Reaper's Rap is [1/Game] and needs a Calliope in the center; Memento Mori needs 4 cheers. Harusaki Nodoka, SorAZ Celebration, Bloom Stage and Archive PC are LIMITED, so only one of them a turn. The deck draws and archives a lot: in the 60-game test the trained AI lost one game by running out of cards.

Game plan

Turns 1–2

Early game

Bloom Calliope early.

  1. Play Normal PC and Friendly PC to get 3+ #EN holomem on stage.
  2. Bloom 1st Calliope hBP06-059 on your 2nd turn for a cheer.
  3. Use SorAZ Celebration and Harusaki Nodoka to find more pieces.
Turns 3–4

Mid game

Get 2nd Calliope out.

  1. Bloom 2nd hBP06-060 around your 3rd or 4th turn.
  2. Collab 1st hBP06-058 to dig, and use Bull's-Eye to add cheers if she is not ready.
  3. Keep Ina behind as support; skip 1st Kiara, whose Arts needs a red cheer this deck does not have.
Turn 5 on

Late game

Double Memento Mori.

  1. Load her with 4 cheers and swing Memento Mori every turn.
  2. Fire Reaper's Rap with Calliope in the center for a second swing.
  3. Use Sampling to bring back lost #EN holomem.

What the trained AI does

In 60 test games the trained AI won 82%, against 70% for the JP Myth Reunion AI playing the same deck. It finished games in about 8 of its own turns.

Friendly PC played per game0.681.28Plays fewer PCs (Normal PC 0.85 vs 1.30).

Practice it

  1. In Match Lab's Player vs Bot, play against the Myth Reunion (EN pool) Specialist AI first and watch how it sets up.
  2. Then pilot the deck yourself: bloom 1st Calliope hBP06-059 on your 2nd turn, and save 2 holo power so Reaper's Rap is ready for a double Memento Mori around your 6th turn.
  3. Aim to win in about 8 of your own turns, like the trained AI does.
