The 4 combo pieces

What must be in place

There are at least X counters on artifacts, creatures and/or enchantments you control, where X is 3 plus the number of times you've cast Sin from the command zone this game.

How to execute it

  1. Cast Sin either from your hand or command zone by paying {5}{G}{U} plus commander tax if applicable.
  2. As Sin enters, remove all counters from all artifacts, enchantments and creatures you control, putting twice that many +1/+1 counters on Sin.
  3. Activate Arbor Adherent by tapping it, adding an amount of {G} or {U} equal to Sin's toughness.
  4. Activate Aura of Dominion by paying {1} and tapping Sin, untapping Arbor Adherent.
  5. Activate Phyrexian Altar by sacrificing Sin, adding {G/U}.
  6. Choose to return Sin to the command zone from your graveyard.
  7. When Sin dies, it triggers, putting its counters on Arbor Adherent.
  8. Repeat.
