Echocasting Symposium + Phage the Untouchable

단계

1. Cast Echocasting Symposium by paying {4}{U}{U}, causing an opponent to create a token copy of Phage and exiling Echocasting Symposium.
2. When the Phage token enters, it triggers, causing its controller to lose the game.
3. During your next turn, at the beginning of your precombat main phase, Echocasting Symposium's paradigm ability triggers, causing you to cast a copy of it from exile. Resolve the copy, causing an opponent to create a token copy of Phage.
4. Repeat from step 2.
