u/g combo infect commnt

saw this on ggs in legacy, i think it adapts well into standard as well. ive been play testing it all day it wrecks caw-go, valakut, and u b control from what ive tested, but it has some issue with vamps, b c of all the spot removal. any ideas? 20 lands has been working fine but i might up it to 22 for sustainibility. id cut the sledges,or 2 groundswell. although they both work very well. the gameplan is this. turn 1 glistener or inkmoth, turn two swing + 2 mana pumps (if elf) and then phyrexian mana pumps. this deck can win turn two, but its not likely. the gambits provide sustainability and extra counters. sideboard is easy. mistep is main b c heres so much red and condemns in the format, not to mention inquisition. sub in 4 flashfreeze vs valakut take out leaks, or misteps if your more worried about clasm than bolt. pierces are vs vamps. sounds dumb but arc trail is a beating same with bolt. also good for dodging doj. clasp is also for vamps, good removal for alot of theyre one drops. also for caw, attrition is good =d. corrupters are pretty strait forward. ideas?
