Hawkeye's Bow + Kiora's Follower + North Pole Patrol

Hawkeye's Bow

Kiora's Follower

North Pole Patrol

How it works

1. Activate Kiora's Follower by tapping it, targeting North Pole Patrol.
2. If Kiora's Follower has Hawkeye's Bow attached to it, Hawkeye's Bow triggers, dealing 1 damage to each opponent.
3. Resolve the Kiora's Follower ability, untapping North Pole Patrol.
4. Activate North Pole Patrol by tapping it, targeting Kiora's Follower.
5. If North Pole Patrol has Hawkeye's Bow attached to it, Hawkeye's Bow triggers, dealing 1 damage to each opponent.
6. Resolve the North Pole Patrol ability, untapping Kiora's Follower.
7. Repeat.

This elegant loop relies on a mutual untapping partnership between Kiora's Follower and North Pole Patrol, where each creature uses its tap ability to untap the other endlessly. By outfitting one of them with Hawkeye's Bow, every time that creature taps to use its ability, the equipment's triggered ability fires off and deals damage to each opponent. Because the bow only costs {1} to equip, you can easily shift it to whichever creature is currently doing the tapping, turning a simple untap engine into infinite damage.
