Isochron Scepter + To Arms! + North Pole Patrol

Isochron Scepter

To Arms!

North Pole Patrol

How it works

1. Activate any number of creatures by tapping it, adding at least 2.
2. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of To Arms! without paying its mana cost.
3. Resolve the copy of To Arms!, untapping all creatures you control and causing you to draw a card.
4. Activate North Pole Patrol by tapping it, untapping Isochron Scepter.
5. Repeat.
6. If creatures you control can tap to produce at least 3, this combo nets near-infinite mana.

This elegant loop hinges on Isochron Scepter holding an imprinted copy of To Arms!, ready to generate free copies whenever you feed it the necessary mana. To keep the engine running, North Pole Patrol steps in to untap the Scepter each iteration, while the untap effect from To Arms! simultaneously resets your mana-producing creatures. This lets you cycle through your deck, netting near-infinite card draw and untaps, and even generating massive amounts of mana if your creatures can produce more than the activation costs require.
