The 4 combo pieces

What must be in place

Dual Casting attached to a creature you control that does not have summoning sickness.

How to execute it

  1. Cast Caberetti Charm by paying {R}{G}{W}.
  2. Holding priority, activate the creature with Dual Casting attached by paying {R} and tapping it, copying Cabaretti Charm.
  3. Resolve the copy of Cabaretti Charm, creating two 1/1 Citizen creature tokens.
  4. When the Citizen tokens enter the battlefield, Intruder Alarm triggers twice, untapping all creatures.
  5. Activate Phyrexian Altar by sacrificing a Citizen, adding {R}.
  6. Repeat from step 2.
  7. Once you have an arbitrarily large number of creature tokens, you may instead choose any of Cabaretti Charm's modes to deal infinite damage to any creature(s) and planeswalker(s) and/or get infinitely large creatures until end of turn.
