How to execute it

  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.

  6. If creatures you control can tap to produce at least {4}, this combo nets infinite mana.
