Ephemerate + Skullwinder + Time Warp

Ephemerate

Skullwinder

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 Skullwinder and exiling Ephemerate.
3. When Skullwinder 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 Skullwinder.
6. When Skullwinder enters, it triggers, returning Ephemerate from your graveyard to your hand.
7. Repeat.

This brilliant loop locks down the game by chaining infinite turns through precise graveyard recursion. By casting Time Warp, you secure the extra turns needed to keep your engine running, while Ephemerate provides the repeatable blinking power necessary to reset the loop. Each time Ephemerate blinks Skullwinder, its enters-the-battlefield ability triggers to fish Time Warp back to your hand, and thanks to Ephemerate's rebound ability, you get a free cast on your upkeep that even recycles the Ephemerate itself back to your hand for the next cycle.
