How it works
Cast Storm Herd by paying 8, causing you to create a number of 1/1 Pegasus creature tokens equal to your life total and a 1/1 Soldier creature token.
At the beginning of your next upkeep, Mayael's Aria triggers, causing you to put a +1/+1 counter on each creature you control, gain ten life and win the game.
