A few days ago, I drafted a zoo-centric Warlock with triple Darkshire Councilman and went 3-3. Today, I drafted another zoo-centric Warlock deck with one Councilman, a handful of deathrattle minions, and double Undertaker. Currently at 4-1 with some close calls. Kabal Courier is some great glue when it gets lucky. I got Antonidas versus a Druid at 3-1; it wasn't even close. A mage lost to my Argent Commander topdeck and Knife Juggler in hand with said Mage at 5...only 3 targets to hit, but one was Hogger, Doom of Elwynn, and he also had lethal. A paladin lost after Kabal Courier gave me Kazakus and I drew the first Undertaker (my only duplicate) around turn 9. I did the 8 damage, gain 10 armor potion. Thought I had lethal with a Soulfire afterward, but accidentally got the armor and damage amounts mixed up in my head. The Paladin nearly won, but Evil Genius came off the top and gave me Kobold Lackey.
Why I picked Undertaker twice: First time, it was with Duskboar and Clockwork Automaton, the latter of which is the worst pick ever in a Warlock draft no matter what else is there. Second time, I was like "Yeah, sure." with Corruption and Sense Demons.
EDIT: Went 4-3. Still got Chef Nomi out of the pack.
Went 10-3, best run so far. Lost the last 2 matches to the exact same paladin guy, who had 3 equality in his deck. My deck had 3 spellstones and several weapons to buff them up, also frothing berserker and whirlwind which I used to pull off some wombo combo.
