The 4 combo pieces

What must be in place

Pentavus does not have a -1/-1 counter on it.

How to execute it

  1. Activate Cauldron of Souls by tapping it, giving Pentavus persist until end of turn.
  2. Activate Ashnod's Altar by sacrificing Pentavus, adding {C}{C}.
  3. When Pentavus dies, its persist ability triggers, returning it from your graveyard to the battlefield with four +1/+1 counters on it.
  4. Activate Pentavus' first ability twice by paying {2} and removing two +1/+1 counters from it, creating two 1/1 Pentavite artifact creature tokens.
  5. Activate Clock of Omens by tapping Pentavus and a Pentavite, untapping Cauldron of Souls.
  6. Repeat.
  7. Once you have infinite colorless mana and Pentavite tokens, you may use Pentavus' second ability to put infinite +1/+1 counters on it.
