Mayael's Aria + Tyvar, the Pummeler

Mayael's Aria

Tyvar, the Pummeler

How it works

1. At the beginning of your upkeep, Mayael's Aria triggers.
2. Holding priority, activate Tyvar by paying 3, giving creatures you control +X/+X until end of turn, where X is the greatest power among creatures you control.
3. If you do not control a creature with power 19 or greater, repeat from step 2.
4. 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 clever loop centers on Mayael's Aria, using its upkeep trigger as a window to explosively scale your board's power rather than just relying on what's already there. By repeatedly activating Tyvar, the Pummeler's hefty pump ability with priority retained, you can continuously boost your creatures' power until you cross the crucial threshold. Once that massive power requirement is met, the resolving Mayael's Aria trigger effortlessly checks off all its conditions at once to secure an immediate victory.
