Intruder Alarm
Maskwood Nexus
Karn, the Great Creator

Requires
Intruder Alarm must be on the battlefield. Maskwood Nexus must be on the battlefield. Karn, the Great Creator must be on the battlefield.
Steps
  1. Activate Karn's first loyalty ability by putting a loyalty counter on it, causing Maskwood Nexus to become a 4/4 artifact creature until end of turn.
  2. Activate any number of mana-producing creatures you control by tapping them, adding at least 3.
  3. Activate Maskwood Nexus by paying 3 and tapping it, creating a 2/2 Shapeshifter creature token.
  4. When the Shapeshifter enters the battlefield, Intruder Alarm triggers, untapping all creatures.
  5. Repeat from step 2.
  6. If creatures you control can tap to produce at least 4, this combo nets infinite mana.
Results
Infinite creature tokens. Infinite ETB. Infinite mana creatures you control can produce. Infinite untap of creatures.
