In my experience, Landstill and Combo tend to be the bad matchups. I am lucky in that I don't run into too much combo here in the Charlotte, NC area but both can be problems. The combo I have played against and struggled with at some point is Belcher and Solidarity. Belcher is one of those deals where you either have the answer or you don't. Null Rod and Disenchant work extremely well as would be imagined. As for Solidarity, unless I am missing something this is the decks worste matchup. True Beleiver and Orim's Chant do nothing. You can protect true beleiver with MoR all you want but evacuation just kills you out of the sideboard. Orim's Chant simply delays the inevitable by one turn.
As for Landstill, I have played it a few times and have gone about 50/50 against the deck. I qualify this by saying I have played very few matches against the deck to even suggest that the matchup is 50/50 as I suspect it is far worse.
As for good matchups ... the deck has many. Anything Red based tends to be fairly easy. I also have a pretty easy time against teh R/G based Survival decks. ATS is a bit more problematic but nothing a good player shouldn't be able to handle. I have also had good experiences against Rock variants of numerous fashion. Control, excepting for Landstill, is also something I have come to see as a good matchup. Scepter-Chant can be a bit problematic if you run into it often, God knows I have over the past couple months, but non-scepter control tends to simply be a game of play a threat early and beat down ... a la Jamie Wakefield.
