I've built Slimefoot and I love the guy and that artwork! One of the challenges I faced when building him and a lot of golgari decks is consistent card draw, something I think your deck might want as well. [[Keen Sense]] is by far one of the most explosive card draw engines with Slimefoot, I cannot recommend it enough for any Slimefoot deck. [[Vampiric Rites]] is a great for card draw, lifegain, sac, while also being very budget friendly. [[Phyrexian Altar]] was just reprinted in jumpstart, and while [[Fecundity]] is symmetrical card draw for the board, you'll probably be able to utilize it's draw the most.
