Kykar, Zephyr Awakener + Temporal Manipulation + Ardent Elementalist

Kykar, Zephyr Awakener

Temporal Manipulation

Ardent Elementalist

How it works

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