The 4 combo pieces

What must be in place

Elite Arcanist does not have summoning sickness.
It is your turn.

How to execute it

  1. Activate Elite Arcanist by paying {0} and tapping it, casting a copy of Pact of the Titan without paying its mana cost.
  2. Chakram Retriever triggers, untapping Elite Arcanist.
  3. Resolve Pact of the Titan, creating a 4/4 Giant creature token.
  4. Repeat an arbitrarily large number of times.
  5. Deal combat damage to each opponent using the Giants, causing them to lose the game due to having zero or less life.
