Celestial Convergence + Thief of Blood

Celestial Convergence

Thief of Blood

How it works

1. Cast Thief of Blood by paying 4.
2. When Thief of Blood enters the battlefield, it triggers, removing all counters from all permanents and putting a +1/+1 counter on it for each counter removed this way.
3. At the beginning of your next upkeep, Celestial Convergence triggers, causing you to win the game.
