Echocasting Symposium + Greenwarden of Murasa + Time Warp

Echocasting Symposium

Greenwarden of Murasa

Time Warp

How it works

1. Cast Time Warp by paying its mana cost, causing you to take an extra turn after this one.
2. Move to 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.
3. Resolve the copy, creating a token copy of Greenwarden of Murasa
4. When the Greenwarden of Murasa token enters, it triggers, returning Time Warp from your graveyard to your hand.
5. Repeat.

This mesmerizing loop uses Echocasting Symposium’s clever paradigm mechanic to repeatedly cast copies of the spell from exile without paying its mana cost during your main phases. Each copied casting targets your creature to create a token copy of Greenwarden of Murasa, whose entrance trigger instantly fishes Time Warp back out of your graveyard and into your hand. Because Time Warp grants you an endless succession of extra turns, you perpetually reset your main phases to cast the Symposium anew, locking down the game under a mountain of uninterrupted actions.
