Echocasting Symposium + Skullwinder + Walk the Aeons

Echocasting Symposium

Skullwinder

Walk the Aeons

How it works

1. Cast Walk the Aeons 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 Skullwinder
4. When the Skullwinder token enters, it triggers, returning Walk the Aeons from your graveyard to your hand.
5. Repeat.

This brilliant loop grants you infinite turns by chaining extra time together, powered by the incredible recurring value of Walk the Aeons. By utilizing Echocasting Symposium and its unique paradigm ability, you can repeatedly cast a free copy of the spell at the beginning of each of your first main phases to continuously make token copies. Each of those token copies brings along Skullwinder, whose entry trigger lets you constantly pull Walk the Aeons right back out of your graveyard and into your hand to keep the chain unbroken.
