Ephemerate + Temporal Manipulation + Possessed Skaab

Ephemerate

Temporal Manipulation

Possessed Skaab

How it works

1. Cast Temporal Manipulation by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Ephemerate by paying , blinking Possessed Skaab and exiling Ephemerate.
3. When Possessed Skaab enters, it triggers, returning Temporal Manipulation 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 Possessed Skaab.
6. When Possessed Skaab enters, it triggers, returning Ephemerate from your graveyard to your hand.
7. Repeat.

This clever engine achieves infinite turns by looping a continuous sequence of spells with the help of Possessed Skaab. When you cast Temporal Manipulation and take an extra turn, Ephemerate steps in to blink the Skaab and retrieve the extra-turn spell from your graveyard, all while its rebound ability ensures you can recast the blink spell for free on your next upkeep. Because Possessed Skaab's replacement effect exiles it whenever it would die, the creature safely stays out of the graveyard while constantly recycling your key spells. The result is a seamless, self-sustaining loop that locks the game down by granting you endless consecutive turns.
