Voltaic Construct + Transmogrifying Licid + Howlsquad Heavy

Voltaic Construct

Transmogrifying Licid

Howlsquad Heavy

How it works

1. Activate Howlsquad Heavy by tapping it, adding at least .
2. Activate Voltaic Construct by paying 2, untapping Howlsquad Heavy.
3. Repeat

This explosive loop relies on Howlsquad Heavy’s max speed ability to generate a massive burst of red mana by tapping, which is then endlessly refueled by Voltaic Construct's ability to untap artifact creatures for just two mana. The crucial linchpin making this all work is Transmogrifying Licid, whose ability turns the Heavy into an artifact in addition to its other types—transforming it into a legal and willing target for the Construct's untapping machinery.
