Reading your comments and thinking about the meta actually made me want to change the structure of my deck, and going more for mana denial.
Roiling Terrain + SoBaM proved to be a nice synergy while playtesting, RT isn't bad even alone, usually dealing 3-5 damage due to fetch lands/KotR. Also, against Dredge it's nuts. For other LD, I ran
Stone Rain and
Aftershock +
Goblin Ruinblaster
@Equipment, I added 2 SoBaMs but kept Jitte count at 1. Without
Gathan Raiderseven two seems too much..
I might post the deck list in case someone's interested.
