Aqua Vibrato ×4
Role: Early play (draw + change source)
Draw 1 when it enters. It helps assemble key pieces, and changing into Karakureversi, Geima Treacherous Fox next turn is one of the ideal moves. The 2-cost you most want to put out.

Based on [Water Fire Magic] itself, which reigned at the top of the environment for about a year from autumn 2023. In terms of track record, it's among the best of the 25 decks.
The key is "Revolution Change," where a creature swaps in from hand when one attacks. With the trump cards Karakureversi, Geima Treacherous Fox and Kakumeijin, Geima King Dragon, it fires off disruption spells and untap spells repeatedly, delivering undefendable consecutive attacks — a hyper-aggressive and technical deck. True to its title, 3-turn kills happen routinely. With its many draw sources it can handle long games too, and its customization range is wide.
Starting from a 2-cost Magic creature, prepare a Revolution Change source → Karakureversi, Geima Treacherous Fox → re-attack via untap spell → into Kakumeijin, Geima King Dragon, or change directly into Kakumeijin, Geima King Dragon from the cost 5 Napoleon Vibes → attack consecutively while cheating spells (untap, disruption) before breaks, shave the opponent's shields, and win with a direct attack.

Role: Early play (draw + change source)
Draw 1 when it enters. It helps assemble key pieces, and changing into Karakureversi, Geima Treacherous Fox next turn is one of the ideal moves. The 2-cost you most want to put out.

Role: Magic reduction + change source
Once per turn, reduce a Magic's cost by 1. With Just Diver, the turn you put it out it can't be chosen and isn't attacked, so it survives easily. There's also the route of this on turn 2 → involving the reduction on turn 3 for Napoleon Vibes → Kakumeijin, Geima King Dragon. It's also used to attack consecutively by involving ♪ Speed of Sound, During a Performance, Tuning when closing.

Role: Piggyback draw + bounce
The creature side piggybacks on the opponent's 2nd or later draw to draw too. With "Magic Friend Burst," tapping another Magic lets you immediately use the spell side (return 2 opponent elements to hand) for 2 cost. From the mid game on, effective for pushing an attack through by clearing away an obstructive creature. You can also land it with Perfect Coldflame.

Role: Change source + consecutive attacks
The creature side is a Speed Attacker that immediately becomes a change source, and with "Mega Last Burst" it cheats the spell side when it leaves. The spell side grants Speed Attacker to one ally + untaps it after its first attack. You can start attacking from an empty board. The key to chained attacks is that swapping via Revolution Change resets "the first attack."

Role: Direct change source + hand exchange
Cost -1 if a Magic is present. When it enters, discard up to 2 from hand + draw 1 extra (draw 1 even discarding 0). Speed Attacker, Double Breaker. Being cost 5, it can change directly into Kakumeijin, Geima King Dragon. The spell side destroys all opponent cost 2 or less elements, peeling off light meta or Blockers.

Role: Relay point (jack-of-all-trades)
G-Strike, Revolution Change from Magic, Speed Attacker. When it enters, draw 1 + cheat a cost 3 or less spell from hand. Ideally use ♪ Speed of Sound, During a Performance, Tuning or Perfect Fire on itself to untap → change into Kakumeijin, Geima King Dragon on the re-attack. Depending on the situation you can also choose Perfect Coldflame or ♪ A Thin Frog, Lucky Number is Here.

Role: Finisher
Revolution Change from a cost 5 or more Magic. Double Breaker, grants Speed Attacker to all your Magics. Before each break, cheat a spell whose cost is at or below your mana count from hand/graveyard (basically twice with Double Breaker). Reserve an untap spell with one, and use the other to counter triggers or set up with Perfect Coldflame. Your mana count directly affects the quality of usable spells.

Role: All-purpose chained-attack support
Choose twice from "cheat a cost 3 or less creature" / "grant Speed Attacker" / "untap after the first attack." Basically grant untap to create chained attacks. Cheating out trigger-countering creatures like Magnum, Shortshot or Synchro Faerie is also frequent.

Role: All-purpose spell (hand exchange / stall / cheat)
Becomes a Shield Trigger with 2 or more spells in the graveyard. Choose twice from "lock attack/block" / "discard 1, draw 2" / "put a cost 2 or less element into play." Early on, use hand exchange to find pieces, also for breaking through Blockers or securing a change source. When cheating it from Kakumeijin, Geima King Dragon, pick the optimal mode.

Role: Technical disruption
Shield Trigger. Draw 1, declare a number, ignore the abilities of opponent elements of that cost + lock spells of that cost. Basically cast it from Kakumeijin, Geima King Dragon, declaring the cost of a Shield Trigger spell you don't want to come out to lock it. It requires knowledge of the costs of the opponent's cards. Note it doesn't affect elements that come out after you cast it.

Role: Trigger soak + removal
The creature side draws all the opponent's choices to itself; adding it during an all-out attack soaks up the removal of Shield Triggers and G-Strikes. Even if removed, "Mega Last Burst" lets you use the spell side (return an opponent creature to hand + draw 1), so no loss. Can also be landed with Perfect Coldflame.

Role: Shield Trigger creature counter
The strongest trigger counter, making opponent creatures that would come out during your turn go to the graveyard. Adding it before an all-out attack is reassuring. The awkward point is that being cost 3 it creates an opening when landing. If you need it to break through, find it with Perfect Coldflame or put it out from Perfect Fire.

Role: Aggro suppression + stall
The creature side makes a creature unable to attack that turn when an opponent creature enters (draw 1 if cheated). Basically use this to delay the opponent's attack by one turn. Since the effect is per creature, it continues even if removed. The spell side makes an opponent creature of the specified cost unable to attack/block, used for breaking through Blockers.
Prepare a Magic creature on turn 2 to set up a Revolution Change source and your hand. Top priority is Aqua Vibrato, but if you have Napoleon Vibes and can move on turn 3, you may prioritize Assister Mogiringo. You want to assemble Kakumeijin, Geima King Dragon, its change source, and an untap spell. If they don't come together, don't jump the gun — search with Perfect Coldflame.
Before moving, decide "rush on turn 3, or attack on turn 4 with disruption." A turn-3 start is intense but tends to leave your hand and trigger countermeasures insufficient; turn 4 loses speed but allows a rock-solid attack involving ♪ Rising up, Demon and Angel, will they fall. Judge by the opponent's defensive hardness and speed. Routes: ① Magic attack → Karakureversi, Geima Treacherous Fox → untap → Kakumeijin, Geima King Dragon; ② direct change into Kakumeijin, Geima King Dragon from Napoleon Vibes. Clear away/stop the opponent's Blockers before breaks.
Once Kakumeijin, Geima King Dragon's break is assured, cheat spells whose cost is at or below your mana from hand/graveyard (basically graveyard) equal to the number of breaks. First set up the situation with any spell, then on the second use an untap spell on itself to reserve untap. Changing Kakumeijin, Geima King Dragon → Kakumeijin, Geima King Dragon and using an untap spell again revives "the first attack" for a re-attack. Soak the opponent's G-Strikes and removal triggers with Synchro Faerie while closing out at once.
A hyper-aggressive and technical proven deck that delivers consecutive attacks by repeatedly firing Revolution Change and untap spells. Swing through while disrupting via Kakumeijin, Geima King Dragon's spell cheating. The key is judging between a turn-3 start and a turn-4 disruption attack. Its weaknesses are multifaceted disruption and the difficulty of plays requiring opponent knowledge. Highly polished, and you can enjoy customizations that change civilizations and format.
