If you have a full collection and want to play something grindy and competitive, this is a good deck to be on. It struggles against things with warded and armor, as most of the removal is dependent on pinging things, and opposing Gama Sennins can be tricky to deal with. If you're okay losing some matchup equity for what's pretty even to favorable against the rest of the field, then I wouldn't make any changes to this list. And if you're wondering, I find the YP matchup slightly favorable (probably a 55/45, if we're being honest).
