We did it! I can officially say I've won my very first FNM.
Round 1, UWR Control, 2-0. Game 1 I put a lot of pressure on the board. He played the legendary turn 4 Supreme Verdict. But I was smart and didn't over commit, so I played a Goblin Rabblemaster the turn after the verdict and won. Game 2 he was land screwed after a mulligan to 6 and you can't be land screwed against Rabble Red.
Round 2, MGD (Mono Green Devotion), 2-1. Game 1 I had lots of creatures that said "creatures can't block" so lots of his creatures were pointless. I also had a lot of burn and got a lot of damage through. Game 2 he did what Monk Green did and took a 2 min turn adding mana to his mana pool, and playing cards. After getting him to 3 I just couldn't draw a burn spell to finish the job. Game 3 I kept a terrible hand of 4 land, Dynacharge, Chandra, Pyromaster, and Stoke the Flames. I did draw a creature turn 2 and turn 3 so it's not like I was waiting until turn 4 to do anything. But I won because of the Chandra. He had nothing but Elvish Mystics out and every turn I killed one off until he was stuck on two lands. I used my next few draws of creatures to finish the job.
Round 3, Naya Midrange, 2-0. Game 1 none of his creatures scared me because I had "can't block" creatures. Game 2 even after keeping a hand of double Anger of the Gods he missed his 3rd land drop and played turn 4 anger and turn 6 anger. I did overcommit not expecting a second anger but I had a Stoke the Flames in hand and he was at 4 thanks to taking 1 from Battlefield Forge.
Round 4, UW Control, 2-0. Game 1 I was too fast and again, didn't over commit. His turn 4 Supreme Verdict was not very impressive after I landed a rabble master the turn after. He was also stuck on lands. Game 2 he had the elixir out. I got him to 3 after he stabilized. He cracked elixir and in response I played Lightning Strike.
So, I was the only 4-0 so I got 6 packs, a promo Banishing Light (which by the way is terrible. Never kill Chromanticore kids), and I did win a door prize of an additional pack from the prerelease box.
