Marwyn, the Nurturer + Ringing Strike Mastery

Marwyn, the Nurturer

Ringing Strike Mastery

How it works

1. Activate Marwyn by tapping it, adding at least six
2. Activate Ringing Strike Mastery by paying 5, untapping Marwyn.
3. Repeat.

This loop transforms Marwyn, the Nurturer into a self-contained mana engine once her power reaches six or greater. By using the green mana generated from her tap ability to pay for Ringing Strike Mastery's untap activation, you can repeatedly untap Marwyn to tap her for a profit. Because Ringing Strike Mastery keeps the enchanted creature locked down during your untap step, its activated ability becomes the crucial engine that bypasses the normal rules of the game to keep the mana flowing indefinitely.
