Kykar, Zephyr Awakener + Time Warp + Donnie & April, Adorkable Duo

Kykar, Zephyr Awakener

Time Warp

Donnie & April, Adorkable Duo

How it works

1. Cast Time Warp by paying its mana cost.
2. Kykar triggers, exiling Donnie & April.
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 Donnie & April from exile to the battlefield.
5. When Donnie & April enters, it triggers, returning Time Warp from your graveyard to your hand.
6. Repeat each turn.

This brilliant loop locks down infinite turns by turning a single extra-turn spell into a permanent engine. You kick things off by casting Time Warp to claim your next turn, while Kykar, Zephyr Awakener watches from the battlefield and uses its noncreature spell trigger to exile Donnie & April, Adorkable Duo. When that extra turn reaches its end step, Kykar brings Donnie & April back to the battlefield, triggering their arrival ability to scoop Time Warp right back out of your graveyard and into your hand. Because Kykar's blink effect safely hides the duo away until the end step, you get to repeat this cycle every single turn for an unbroken sequence of extra turns.
