How it works
- Activate Gyre Engineer by tapping it, adding .
- Activate Gyre Engineer by paying 1 and untapping it, giving itself +2/+2 until end of turn.
- Repeat.
This dazzling sequence harnesses the cost-reducing power of Training Grounds to turn Umbral Mantle into an engine of boundless growth and resources. Because Training Grounds lowers the activation cost of the Mantle's untap ability from {3} down to the minimum of {1}, Gyre Engineer can untap itself for less mana than its own tap ability produces. By endlessly tapping Gyre Engineer for green and blue mana and paying that discounted price to untap it with the Mantle equipped, you generate an infinite surplus of mana while inflating the Engineer's size to cosmic proportions.
