Devilish Valet

Mayael's Aria

Phylath, World Sculptor

Vivien, Champion of the Wilds

How it works

1. At the beginning of your upkeep, Mayael's Aria triggers.
2. Holding priority, cast Phylath by paying 4.
3. Phylath enters the battlefield, triggering itself and Devilish Valet.
4. Resolve the Phylath trigger, creating a 0/1 Plant creature token for each basic land you control.
5. Each Plant token enters the battlefield, triggering Devilish Valet that many times.
6. Resolve a Devilish Valet trigger, doubling its power until end of turn.
7. Repeat step 6 for each remaining Devilish Valet trigger.
8. Resolve the Mayael's Aria trigger, causing you to put a +1/+1 counter on each creature you control, gain ten life and win the game.
