I went 3-1 last Friday.
1st match: Jund Reanimator 2-0
I did a lot of early damage and he wasn't quick enough. I handled a turn 4 Angel of Serenity with Putrefy on my turn.
The 2nd game was nearly the same... My creatures did a lot of damage and I handled a Boros Reckoner with my Dreadbore.
2nd match: Naya midrange 2-0
My opponent was a beginner so nothing special happened. I rushed her and she wasn't able to do anything against my fast creatures. She only had a Predator Ooze wich wasn't a real threat.
3rd match: Boros Aggro 2-1
My opponent had mana problems in game 1 so it was an easy game again. I got mana screwed in game 2. game 3 was really narrow. Both decks did a lot of early damage and I won with only 1 life left because of Tajic, Blade of the Legion and 2 Rakdos Cackler.
4th match: Jund reanimator 0-2
I got mana screwed in the first game... I only had 2 mana the whole game so it was an easy win for my oponnent. He was lucky in game 2. T1 Arbor Elf, T2 Loxodon Smiter, T3 2x Voice of Resurgence. He also had a Gavony Township. I was able to kill the voices and the Arbor Elf with a 4/4 Experiment One and removal. so he had a 5/5 Smiter and 2 4/4 tokens left and I wasn't able to kill them.
After FNM I updated my sideboard to be more effective.
Also I'm not sure if I should play Rakdos Cackler or Diregraf Ghoul... the cackler has easier mana costs but the ghoul is able to block and gives me a +2/+2 counter for b if my Varolz, the Scar-Striped is out.
