Given the fact Thriving Rats was added now, I think we have enough 2 drops in the common slot to warrant two 2 uncommon aggro drops. The main issue I have with Fretwork Colony is it's only good on turn 2 or 3, and unplayable anytime else. This makes it a bad cube card. Ovalchase Daredevil needed to go in no matter what, so I'll make this swap.

If Sly Requisitioner needs to come out, Fretwork Colony will go back in.
