Intruder Alarm + Sprout Swarm

Intruder Alarm
Sprout Swarm

Requires
Intruder Alarm must be on the battlefield. Sprout Swarm must be in hand.
Steps
  1. Cast Sprout Swarm with buyback by tapping five untapped creatures you control, creating a 1/1 Saproling creature token and returning Sprout Swarm to your hand.
  2. The Saproling enters the battlefield, triggering Intruder Alarm, untapping all creatures.
  3. Repeat.
Results
Infinite creature tokens. Infinite ETB. Infinite magecraft triggers. Infinite mana creatures you control can produce. Infinite storm count. Infinite untap of creatures.
