I just had a genius idea on the DD sets...what if you ran a focus sash and switched in on something that you could force out. From the switch is you're 1st DD, then a second DD in the face of your counter while you endure their attack with the sash...now you have a +2/+2 Rayquaza w/ 3 moveslots of destruction...Sure it requires some support, but after all, every set does...
On a similar note, does Air Lock negate the residual damage from sand and hail?
