Medomai the Ageless + Identity Thief + Felhide Spiritbinder

Medomai the Ageless

Identity Thief

Felhide Spiritbinder

How it works

1. Declare Medomai the Ageless and Felhide Spiritbinder as attackers.
2. When Medomai the Ageless deals combat damage to a player, it triggers, causing you to take an extra turn after this one.
3. When Felhide Spiritbinder untaps in your next extra turn's untap step, it triggers, allowing you to pay 1 to create a token copy of Identity Thief with haste.
4. Declare the Identity Thief token and Felhide Spiritbinder as attackers.
5. The Identity Thief token triggers, exiling Medomai the Ageless, becoming a copy of Medomai the Ageless until end of turn, and creating a delayed triggered ability.
6. When the Identity Thief token deals combat damage to a player, it triggers, causing you to take an extra turn after this one.
7. At the beginning of your end step, the delayed triggered ability from step 5 triggers, returning Medomai the Ageless from exile to the battlefield.
8. Let the Identity Thief token die to the legend rule.
9. Repeat from step 3 each turn.
