The 3 combo pieces

What must be in place

You have enough mana to cast the creature with MV<=1 if it doesn't have {X} in its mana cost, or {1} available otherwise.

How to execute it

  1. Cast the creature with MV<=1 by paying its mana cost if it doesn't have {X} in its mana cost, or by paying {1} otherwise, causing the creature to enter the battlefield with a +1/+1 counter on it.
  2. Activate Phyrexian Altar by sacrificing the creature, adding {1}.
  3. When the creature dies, Reyhan triggers, putting a +1/+1 counter on Evolution Witness.
  4. Evolution Witness triggers, returning the creature from your graveyard to your hand.
  5. Repeat.
