Marwyn, the Nurturer + Singing Bell Strike

Marwyn, the Nurturer

Singing Bell Strike

How it works

1. Activate Marwyn by tapping it, adding at least seven .
2. Activate Marwyn by paying 6, untapping it.
3. Repeat.

This clever loop turns Marwyn, the Nurturer into a self-contained mana engine by leveraging her own growth to cover the cost of untapping her. While Singing Bell Strike normally locks a creature down with its heavy untap penalty, here that very restriction is weaponized, effectively replacing her natural untap step with a repeatable mana-sink ability that only costs six mana. Because Marwyn's power scales up as your board develops, the green mana she produces easily outpaces the payment required by Singing Bell Strike, resulting in infinite green mana for whatever grand finale you have planned.
