How the deck wins

This is the EN-pool version of Kronii Warden of Time, using only cards in the English card pool through Diva Fever (hBP07), including the hEB01 Summer set and the start decks through hSD19. Compared with the JP list it makes one swap: the hBP09 1st Kronii hBP09-063 becomes a 2nd copy of the Buzz 1st Kronii hBP07-054. The oshi is still Ouro Kronii hBP07-005, with 30 Kronii holomem, 20 support cards and 20 Blue Cheer.

2nd Kronii hBP07-056 is the finisher: You're not ready for me. costs 2 blue + 2 colorless and hits for 80, +100 because your oshi is Ouro Kronii, so 180 (+50 more against red); you may then reattach 1 cheer from her to another #Promise holomem. Her gift, Commander of Time, works only in the center: at the start of your performance phase you may bloom 1 of your other Kronii using a card stacked under her.

The oshi's SP, Warden of Time (4 holo power, [1/Game]), starts an extra turn after this one if your center holomem is a 2nd Kronii, so a 180-damage turn can be followed right away by another. The 2-power [1/Turn] skill draws 2 from the bottom of your deck and archives 1 card from 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 Kronii Warden of Time AI and played 25,000 more games with this list. On the same deals it won 77.8% against the field, up from 73.8% for the JP AI piloting this list (the JP list scored 82.5%).

Key cards

2nd Kronii hBP07-056 (main attacker)

Gift Commander of Time [Center Position Only]: at the start of your performance phase, you may bloom 1 of your other Ouro Kronii using a holomem stacked under this holomem. Arts You're not ready for me.: 80 for 2 blue + 2 colorless (+50 against red), +100 if your oshi is Ouro Kronii; you may reattach 1 cheer from this holomem to another #Promise holomem. 200 HP.

Your finisher; the trained AI does more of its damage with it than the JP AI does.

Ouro Kronii (oshi)

On the Ring of Oblivion, 2 holo power, [1/Turn]: draw 2 cards from the bottom of your deck, then archive 1 card from your hand. SP Warden of Time, 4 holo power, [1/Game]: if your center holomem is a 2nd Ouro Kronii, start an extra turn after this turn.

Keep 4 holo power for the extra turn; the trained AI fires it in 80% of games, around its 5th turn.

2nd Kronii hBP07-055

Bloom Toward a Promised Future: choose 1 #Promise holomem on your stage; it gets Arts+50 this turn. Arts Life Goes On: 90 for blue + colorless (+50 against white). 190 HP.

Bloom it on a knockout turn to give hBP07-056 Arts+50.

1st Kronii hBP01-094

Bloom Kronii-Chiwa!: search your cheer deck for 1 cheer the same color as a #Promise holomem on your stage and send it to a #Promise holomem. Arts Let's Make It an Unforgettable Fes!: 40 for 1 colorless. 120 HP.

Your most-played bloom; it pays for the 4-cheer finisher.

Buzz 1st Kronii hBP07-054

Buzz, 250 HP; if it is downed you lose 2 life. Arts I'm Pretty Shy...uwu: 50 for 1 blue; send the top card of your cheer deck to a Buzz #Promise holomem.

The EN list runs 2 (the JP list ran 1 plus hBP09-063); a sturdy early body, but it costs 2 life if downed.

Debut Kronii hBP07-050

Collab Today's the Day!: if you went second and it is your first turn, you may bloom your center Ouro Kronii with a 1st from your hand. 130 HP.

Lets you bloom on turn 1 when going second.

Ruler of Time -Promise-

LIMITED event. Only if every holomem on your stage has #Promise: reveal 2 #Promise holomem from your deck and add them to your hand. If your life is lower than your opponent's, one holomem on your stage gets Arts+20 this turn.

Your main search card; every holomem in this deck is a #Promise Kronii.

Warden of Time is [1/Game] and only works if your center holomem is a 2nd Kronii when you use it. Ruler of Time -Promise- needs every holomem on your stage to have #Promise (all Kronii do). The Buzz 1st hBP07-054 costs 2 life if it is downed. Totsumachi, Ruler of Time, Borderline Evil Robot and Manager-chan are LIMITED, so only one of them a turn.

Game plan

Turns 1–2

Early game

Bloom as early as you can.

  1. Going second, collab Debut Kronii hBP07-050 on your first turn and bloom your center Kronii with a 1st.
  2. Bloom 1st hBP01-094 to search a Blue Cheer onto a Kronii.
  3. Use Normal PC and Friendly PC (Friendly PC places the any-number Debut hBP01-092) to fill your stage, and Ruler of Time to find your 2nds.
Turns 3–4

Mid game

Get 2nd hBP07-056 in the center by your 3rd turn.

  1. Bloom the 2nd around your 3rd turn and attach cheers until it has 2 blue + 2 more.
  2. Collab 1st hBP01-094 and 2nd hBP07-055 from the back; bloom hBP07-055 on a knockout turn for Arts+50.
  3. Start saving holo power for the SP.
Turn 5 on

Late game

Take the extra turn.

  1. Hit for 180 with hBP07-056 every turn, moving a cheer to the next Kronii.
  2. Fire Warden of Time (once a game) with a 2nd Kronii in the center to take two turns in a row.
  3. Use the 2-power skill to dig when you run low, and Manager-chan or Borderline Evil Robot to refresh your hand.

Practice it

  1. In Match Lab's Player vs Bot, play against the Kronii Warden of Time (EN pool) Specialist AI first and watch how it sets up.
  2. Then pilot the deck yourself: get 2nd hBP07-056 into the center by your 3rd turn, keep 4 holo power for Warden of Time, and bloom hBP07-055 on the turn you need Arts+50.
  3. Aim to win in about 7 of your own turns, like the trained AI does.
