any help would be appreciated, as this is my first attempt to build this deck. currently, i don't have any beast king of the swamp, but i have several other fusion subs (versago, goddess with 3rd eye, etc.), but don't know what to take out for them. i also thought about running pot of avarice in the deck, along with morphing jar, but not sure about them.
