The 5 combo pieces

What must be in place

Fain and Vhal do not have summoning sickness.

How to execute it

  1. Activate Vhal by tapping it, adding at least {C}{C}{C}.
  2. Vhal triggers, giving creatures that share a creature type with it +2/+0 and undying until end of turn.
  3. Activate Viscera Seer by sacrificing it.
  4. Viscera Seer dies, triggering its undying ability, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
  5. Viscera Seer enters the battlefield, triggering Intruder Alarm, untapping all creatures.
  6. Resolve the Viscera Seer ability from step 3, causing you to scry 1.
  7. Activate Fain's second ability by tapping it and removing the +1/+1 counter from Viscera Seer, creating a Treasure token.
  8. Repeat.
  9. Once you have infinite Treasures, you may use them to get infinite Inklings, and thus infinite +1/+1 counters via Fain.
