Kykar, Zephyr Awakener + Timeless Witness + Time Warp

Kykar, Zephyr Awakener

Timeless Witness

Time Warp

How it works

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

This brilliant loop relies on Kykar, Zephyr Awakener as your engine, using its triggered ability to temporarily exile Timeless Witness whenever you cast a noncreature spell. When Timeless Witness returns at the end step, its enter-the-battlefield ability claws Time Warp right back out of your graveyard and into your hand. Casting Time Warp on your newly granted extra turn triggers Kykar all over again, locking your opponents out of the game entirely by taking infinite turns.
