Hawkeye's Bow + Ioreth of the Healing House + Kelpie Guide
Hawkeye's Bow
Ioreth of the Healing House
Kelpie Guide
Infinite damage
How it works
Activate Ioreth of the Healing House by tapping it, targeting Kelpie Guide.
If Ioreth of the Healing House has Hawkeye's Bow attached to it, Hawkeye's Bow triggers, dealing 1 damage to each opponent.
Resolve the Ioreth of the Healing House ability, untapping Kelpie Guide.
Activate Kelpie Guide by tapping it, targeting Ioreth of the Healing House.
If Kelpie Guide has Hawkeye's Bow attached to it, Hawkeye's Bow triggers, dealing 1 damage to each opponent.
Resolve the Kelpie Guide ability, untapping Ioreth of the Healing House.
Repeat.
This clever loop hinges on a mutually beneficial relationship between Ioreth of the Healing House and Kelpie Guide, whose respective untap abilities allow them to endlessly ready one another. To turn that perpetual motion into a victory, Hawkeye's Bow is strapped to whichever creature is actively tapping to ignite the combo. Because the bow triggers every time its equipped creature becomes tapped, each cycle of mutual untapping deals direct damage to your opponents until they are finished off.
