Echocasting Symposium + Temporal Manipulation + Izzet Chronarch

Echocasting Symposium

Temporal Manipulation

Izzet Chronarch

How it works

1. Cast Temporal Manipulation 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 Izzet Chronarch
4. When the Izzet Chronarch token enters, it triggers, returning Temporal Manipulation from your graveyard to your hand.
5. Repeat.

This clever loop leverages Echocasting Symposium’s paradigm ability to recast itself for free on each of your main phases, using the resulting token copies of Izzet Chronarch to endlessly return Temporal Manipulation from your graveyard to your hand. By repeatedly recycling your extra-turn spell, you lock down the game and take all the time you need to secure victory.
