Round 1 was against a new player, scrub and dump.
Round 2 was against a Rakdos deck, he just have the removal. He got me pretty low game 2 with turret ogres, but I amassed so large he had to sacrifice them and I just swung out.
Round 3 was unfortunate. I was spanking the guy, but he was running flyers. I had lethal game 1 for like 3 turns, but I forgot about Law-Rune enforcer's inability to tap armies, so I sacked my 7/7 army to Spark Reaper, thinking it would just be tapped. And so he was able to keep plinking away at me. Game 2, I kept a two land hand and didn't draw any for 4 turns, then was stuck there for 2 more turns. It should have gone to game 3.
