Haha yeah man, Dryad Arbor is pretty cute.

Innocent Blood is certainly a problem for this deck and there really isn't much of anything we get in terms of relief from the board in UR.

If you're seeing a lot of The Gate or other decks running Innocent Blood you've gotta do something to improve your match-up. Dryad Arbor definitely leaves something to be desired, but for pure sneakiness factor in a Sneak Attack deck--I say bravo!
