Mayael's Aria + Devilish Valet + Call the Coppercoats

Mayael's Aria

Devilish Valet

Call the Coppercoats

How it works

1. At the beginning of your upkeep, Mayael's Aria triggers.
2. Holding priority, cast Call the Coppercoats by paying 2, plus 1 any number of times as necessary, targeting any opponent(s) who collectively control five or more creatures.
3. Resolve Call the Coppercoats, creating at least five 1/1 Human Soldier creature tokens.
4. When the Human Soldiers enter the battlefield, Devilish Valet triggers that many times, doubling its power that many times, causing its power to be at least 32 until end of turn.
5. Resolve the Mayael's Aria trigger, causing you to put a +1/+1 counter on each creature you control, gain 10 life and win the game.

This explosive setup turns a modest token spell into an instant-win condition by leveraging Mayael's Aria and its unique upkeep checks. By casting Call the Coppercoats right after your upkeep begins, you flood the board with Human Soldier tokens based on your opponents' creature counts. This sudden influx triggers the alliance ability of Devilish Valet repeatedly, rapidly compounding its power past the critical 20-power threshold needed for Mayael's Aria to hand you the game on a silver platter.
