The Maverick matchup also ranges from slightly unfavorable to slightly favorable, depending on how much spot removal you run. If you're able to shoot down Mother of Runes and win the Knight battles, you are very far ahead. Maze of Ith is very annoying, so running a singleton Wasteland goes a long ways here.
The problem is that this deck sucks pretty hard against a lot of the other popular decks in the format, such as Nic Fit, Sneak Attack, Hive Mind, High Tide, Dream Halls, etc. I'm not sure how the matchup against BUG Control is (I imagine this is extremely heavily dependent on whether you run and assemble Punishing Fire in time). I do like the matchups against Dredge and Reanimator (provided you run Scavenging Ooze and GSZ), and I find Team America, Burn, U/R Delver, Goblins, Merfolk, etc. to be favorable.
As for small Zoo, I find that it is even stronger against RUG Delver as long as you don't get your manabase blown out, but unfortunately, I think it is weaker against Stoneblade and Maverick, as well as the graveyard decks.
