Kykar, Zephyr Awakener + Temporal Manipulation + Mnemonic Wall

Kykar, Zephyr Awakener

Temporal Manipulation

Mnemonic Wall

How it works

1. Cast Temporal Manipulation by paying its mana cost.
2. Kykar triggers, exiling Mnemonic Wall.
3. Resolve Temporal Manipulation, causing you to take an extra turn after this one.
4. At the beginning of your end step, Kykar triggers, returning Mnemonic Wall from exile to the battlefield.
5. When Mnemonic Wall enters, it triggers, returning Temporal Manipulation from your graveyard to your hand.
6. Repeat each turn.

This elegant loop locks down the game by taking infinite turns, giving you all the time you need to secure a win. The engine is fueled by Temporal Manipulation, which grants you the extra turns required to keep the sequence going. Kykar, Zephyr Awakener serves as the crucial enabler, utilizing its triggered ability when you cast a noncreature spell to safely tuck away Mnemonic Wall until the end step. Finally, Mnemonic Wall acts as the recycler, retrieving Temporal Manipulation from your graveyard the moment it blinks back onto the battlefield, ensuring you can cast the extra-turn spell again on your next turn.
