Lore Drakkis + Imaginary Pet + Time Warp

Lore Drakkis

Imaginary Pet

Time Warp

How it works

1. Cast Time Warp by paying 3, causing you to take an extra turn after this one.
2. Cast Imaginary Pet by paying 1.
3. Cast Lore Drakkis for its mutate cost by paying U/RU/R, putting it under Imaginary Pet.
4. Lore Drakkis triggers, returning Time Warp from your graveyard to your hand.
5. At the beginning of your end step, Imaginary Pet triggers, returning itself and Lore Drakkis from the battlefield to your hand.
6. Repeat each turn.
