Echocasting Symposium + Time Walk + Pinnacle Monk // Mystic Peak

Echocasting Symposium

Time Walk

Pinnacle Monk // Mystic Peak

How it works

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

This brilliant Vintage combo achieves infinite turns by continuously recycling Time Walk using the unique delayed casting ability of Echocasting Symposium. Once Echocasting Symposium's paradigm effect is primed, it lets you cast a free copy of the spell at the beginning of each of your first main phases, which creates a token copy of Pinnacle Monk (played on its front face). The entering Pinnacle Monk token's triggered ability immediately returns Time Walk from your graveyard to your hand so you can cast it again on your extra turn, while its prowess ability and the land's red mana production provide a nice supporting framework as you loop toward victory.
