First FNM update:
Went 4-1 with this deck on Friday. Here's the breakdown.
Round 1: 2-0 vs Boros Burn. Both games he tried to blast direct damage to my face, but couldn't outpace the lifegain from the Whip or Blood Baron. His fast creatures were dispatched quickly. No problems.
Round 2: 2-1 vs Bant Hexproof. This was a good matchup. The whole game he kept telling me how much he hates playing against removal decks, then I continually killed everything he played. Devour Flesh and Desecration Demon took care of Witchstalkers. He claims to have drawn poorly in the two games he lost, but from what I saw, I just had answers to everything he played.
Round 3: 0-2 vs Black Aggro (Pack Rats). I was looking forward to this matchup as I knew the deck pretty well. Pain Seers, Tormented Heroes, Rakdos Freaks and Cacklers, Pack Rats. In both games I Downfall/Dark Betrayal'd the first rat to hit the board, but was followed up by a second both times. Also in both games my Desecration Demon (only hope for winning) was Hero's Downfall'd. (two of them in the second game). Opponent admitted he just drew absolutely perfectly against my deck and it should have been much closer. Thems the breaks sometimes.
Round 4: 2-0 vs White Monsters. Not sure what to call what he was playing, but it was weird. Everything ramped to like 4-6 cmc. I was able to swing in with the little guys to get the games out of hand quickly. Any time a monster was dropped it was an easy removal. No issues here.
Round 5: 2-0 vs Simic Evolve. Somehow this deck make it to 3-1 and shooting for top 3. I'm guessing he didn't play against any removal or was just able to outpace any. Both games were over quickly - the first game he didn't cast a single spell. The second wasn't quite as bad, but it still wasn't close.
All in all, I'm happy with the way it performed. My only loss I never really had a chance with my opponent's topdeck being perfect. I'll chalk that up to the random nature of the game sometimes.
