Voltaic Construct + Thran Forge + The Legend of Kyoshi // Avatar Kyoshi

Voltaic Construct

Thran Forge

The Legend of Kyoshi // Avatar Kyoshi

How it works

1. Activate Avatar Kyoshi by tapping it, adding at least five mana of any color.
2. Activate Thran Forge by paying 2, causing Avatar Kyoshi to become an artifact until end of turn.
3. Activate Voltaic Construct by paying 2, untapping Avatar Kyoshi.
4. Activate Avatar Kyoshi by tapping it, adding at least five mana of any color.
5. Repeat from step 3.

This loop transforms the legendary Avatar Kyoshi side of The Legend of Kyoshi // Avatar Kyoshi into a high-powered mana engine by turning it into an artifact creature using Thran Forge's continuous type-changing ability. Once it is an artifact creature, Voltaic Construct can target and untap it for the cost of two mana, completely bypassing the normal restrictions of tapping. Because Avatar Kyoshi’s own tap ability produces mana scaling with the greatest power among creatures you control—which easily outpaces the four total mana needed to activate the forge and the construct—you net a surplus of infinite colored mana while repeatedly untapping your artifact creature.
