edit: Okay, ran the damage calcs (with calculator and notepad, which was kind of annoying) and couldnt find an ev spread for togekiss that can survive a SD'd Dragon Claw or 2 Draco Meteors + SR damage, so Togekiss is out, which means we're still down to claydol and cresselia.
Here are the damage calcs for claydol, since I don't think anyone put them up, and I just wanted to see if claydol actually does counter this thing.
Claydol, Bold, 252 hp, 252 sp atk.
SD'd Dragon Claw on Bold Min Def Claydol 229 - 269 (target hp: 324, 304 w/SR)
Draco Meteor from LOGarchomp to Min Sp Def, neutral natured Claydol: 185 - 218 (target hp: 324, 304 w/SR)
Draco Meteor #2: 62 - 74 (Not enough to 2hko if Claydol is at 100 % hp when it switches in)
Ice Beam from 252 sp atk neutral nature Claydol: 321 - 378 (target hp: after LO drop;321, 357 at 100%)
Your nerfed if your claydol has taken any damage before coming out. Don't know how practical the ev spread is, but it seems to give Claydol the minimum defenses it needs to survive a SDDC or 2 Draco Meteors, and minimum spatk to 100% kill after a LO drop. I'm sure someone else can make a better ev spread than this, but unless you do, don't bash this one.
