Voltaic Construct + Liquimetal Coating + Howlsquad Heavy

Voltaic Construct

Liquimetal Coating

Howlsquad Heavy

How it works

1. Cause Howlsquad Heavy to become an artifact using Liquimetal Coating.
2. Activate Howlsquad Heavy by tapping it, adding at least .
3. Activate Voltaic Construct by paying 2, untapping Howlsquad Heavy.
4. Repeat from step 2.

This clever engine transforms Howlsquad Heavy into a machine by applying Liquimetal Coating, turning it into an artifact creature so it can be targeted by Voltaic Construct. Once Howlsquad Heavy achieves max speed, its tapped ability generates a surge of red mana fueled by your Goblin army. By funneling a portion of that mana into Voltaic Construct to repeatedly untap the Heavy, you loop the process to generate infinite red mana.
