Should play elves. Buddies and I were doing some casual the other day, it was Clerics, UR control, Elves, and Massive green mana ramp (me). Like 4 turns in I had tons of huge creature son the board, clerics had like nothing, UR control had nothing, but they only had 2 creatures in their deck so..., and finally, elves cast fireball for 40 damage on turn 4. Cleric was about to scoop his field when UR put swerve on the stack. that resolved and I lost the game =(
