First time I did well at fnm, so yeah...I'm totally pumped about this!
Anyway things that matter:
round 1: mono-blue devotion
game 1: he was mana screwed early and couldn't do much later on when I had big creatures crawling on the board
game 2: I kept him off his devotion big time! double shadowborns helped a bunch too ;p
2-0
round 2: mono black devotion
game 1: I killed his pack rats at early times so they couldn't clone. No demons on his part. I had the removal and big creatures for game.
game 2: he switched into a faster aggro kill, or just had a better hand. I was close to death and then Gaze of Granite (which i sideboarded in), and whip of erebos for the comeback kill
2-0
rounds 3: white weenie
game 1: I couldn't do anything early and he aggroed me down to 1, then whip of erebos! brought back a nighthowler for 11 and swung with nemesis and shadowborn demon to completely turn the game around!
game 2: He was mana screwed and I simply made sure to abuse that, and do as much early damage as possible.
2-0
round 4: mono green devotion
game 1: Never facing this deck before I wasn't prepared at all. He ramped faster then I could and beat me out with Garruk, caller of beasts.
game 2: First time I had to mulligan all night and was still screwed. He curved out nicely and simply beat me down before I could do anythign which wouldn't have been for a long time.
Both of these games I saw very little removal
0-2
