What must be in place

Feldon does not have summoning sickness.

How to execute it

  1. Activate Feldon by paying {2}{R} and tapping it, creating a token copy of Combat Celebrant with haste.
  2. At the beginning of your combat phase, Determined Iteration triggers, creating a token copy of the Combat Celebrant token with haste.
  3. Declare a Combat Celebrant token as an attacker, choosing to exert it as it attacks.
  4. The token triggers, untapping all other creatures you control and causing you to get an additional combat phase after this one.
  5. Repeat from step 2.
