Intruder Alarm
Maskwood Nexus
Tezzeret, Betrayer of Flesh

Requires
Intruder Alarm must be on the battlefield. Maskwood Nexus must be on the battlefield. Tezzeret, Betrayer of Flesh must be on the battlefield. Tezzeret has at least two loyalty counters on it. Maskwood Nexus does not have summoning sickness. Creatures you control can tap to produce at least 3.
Steps
  1. Activate Tezzeret's second ability by removing two loyalty counters from it, causing Maskwood Nexus to become an artifact creature.
  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 all creatures.
