Agatha of the Vile Cauldron + Hateflayer + Paradise Mantle

Agatha of the Vile Cauldron

Hateflayer

Paradise Mantle

How it works

1. Activate Hateflayer by tapping it, adding .
2. Activate Hateflayer by paying due to Agatha of the Vile Cauldron and untapping it, dealing damage equal to its power to any target.
3. Repeat.

This ingenious loop centers around Hateflayer's untapping damage ability, which is miraculously discounted by Agatha of the Vile Cauldron's power-scaling cost reduction so that it only demands a single red mana to activate. To fuel this directly, the targeted Hateflayer is outfitted with Paradise Mantle, allowing it to tap for the exact mana needed to pay for its own discounted ability. Because Hateflayer untaps as part of its own activation cost, you can repeat this pinging loop indefinitely to deal infinite damage to any target while leveraging wither to wipe out opposing boards.
