Ephemerate + Eternal Witness + Time Warp

Ephemerate

Eternal Witness

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. Cast Ephemerate by paying , blinking Eternal Witness and exiling Ephemerate.
3. When Eternal Witness enters, it triggers, returning Time Warp from your graveyard to your hand.
4. Move to your next turn. At the beginning of your upkeep, Ephemerate's rebound ability triggers, causing you to cast it from exile without paying its mana cost.
5. Resolve Ephemerate, blinking Eternal Witness.
6. When Eternal Witness enters, it triggers, returning Ephemerate from your graveyard to your hand.
7. Repeat.

By looping **Ephemerate** and **Eternal Witness** together, you can turn a single **Time Warp** into an endless succession of extra turns. The engine relies on **Eternal Witness** repeatedly entering the battlefield to fish your key spells back from the graveyard, while **Ephemerate** handles the blinking duties on both the initial casting and through its built-in rebound ability on subsequent turns. This creates an airtight, repeating lock that completely shuts your opponents out of the game by ensuring they never get another untap step.
