Took second with this.  Both the player opposite and I both drafted RWB Removal... and pulled Pack Rat in our RTR pack.  I helped buy the packs too so, just chance that it happened.  First pick was Toil//Trouble.  Far//Away was the standard sideboard out card, usually for Purge the Profane or Fatal Fumes, depending on the matchup

Round 1: 2-0 (RWB Removal)
He got mana-screwed game two, paired with T3 keyrune, T4 pack rat/token while he was tapped out at 2 lands. 

Round 2: 0-2 (GWu)
I misplayed a bit round two, paired with not having enough straight removal (exiled a 2/2 armadillo cloaked creature, only to be staring down a 6/8 vigilance the next turn)

Round 3: 2-0 (RUG)
I pulled Pack Rat both games, probably all I need to say.  I managed to cast Toil//Trouble, with the intent to do 10, only to have it Cancel-ed  (This was the right move, given the information available).  Unfortunately for my opponent, next turn I dropped Pack Rat...

I really liked the deck EXCEPT for Pack Rat.  It just kind of ripped apart my game and said, you're playing Pack Rat.dec now.  I mean, the card's amazing and if you see it, you take it and play it, it's just not fun to play with or against.  Feel like the deck was reasonably good without it.
