Mayael's Aria + Auriok Bladewarden + Sword of the Paruns

Mayael's Aria

Auriok Bladewarden

Sword of the Paruns

How it works

1. At the beginning of your upkeep, Mayael's Aria triggers.
2. Holding priority, activate Auriok Bladewarden by tapping it, giving itself +X/+X until end of turn, where X is its power, which is increased by 2 due to Sword of the Paruns.
3. Activate Sword of the Paruns by paying 3, untapping Auriok Bladewarden.
4. Repeat from step 2 until Auriok Bladewarden has power nineteen or greater, omitting step 3 on the final iteration.
5. Resolve the Mayael's Aria trigger from step 1, causing you to put a +1/+1 counter on each creature you control, gain 10 life and win the game.

This clever loop turns Auriok Bladewarden into an escalating engine by repeatedly tapping it to target itself, parlaying its own growing power into an exponential stat boost. Because Sword of the Paruns not only provides the mana-activated untap to keep the chain going, but also passively pumps the equipped creature's power through its static bonus, each iteration makes the next activation vastly larger than the last. Once Auriok Bladewarden's power surges past the critical threshold of twenty, you simply let Mayael's Aria resolve its upkeep trigger, instantly satisfying its final condition to claim absolute victory.
