My buddy and I were wondering if using Fist of Suns and Morophon, the Boundless would Essentially eliminate the mana cost for whatever particular creature type was chosen. Or if the cards would not work together.
Yes, this works. Fist of Suns grants an alternative cost to your spells, making them cost WUBRG, and Morophon then reduces the spell's cost by WUBRG, making the total cost 0.
