Feldon of the Third Path + Bloodthirster + Determined Iteration

Feldon of the Third Path

Bloodthirster

Determined Iteration

How it works

1. Activate Feldon by paying 2 and tapping it, creating a token copy of Bloodthirster with haste.
2. At the beginning of your combat phase, Determined Iteration triggers, creating a token copy of the Bloodthirster token.
3. Deal combat damage with the Bloodthirster token created by Determined Iteration.
4. The Bloodthirster token triggers, causing you to untap it and to get an additional combat phase after this one.
5. Repeat from step 2.
