Kykar, Zephyr Awakener + Ardent Elementalist + Time Warp

Kykar, Zephyr Awakener

Ardent Elementalist

Time Warp

How it works

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