returning the favour you just gave me beforehand...
might i suggest if you want to use a cresselia that you use the set i have had success with
Cresselia @ Light Clay / Leftovers (obviosly light clay for the screen / leftovers for sunny day, which you probably want)
EVs: 252 HP / 252 SpD / 4 Spe (if you need some guarenteed KO's you can take the SpD and Spe EV's into SpA)
Nature : Calm (+SpD, -Atk)
- Ice Beam
- Light Screen / Sunny Day (i use screen but you need another user of sun and cress is reliable)
- Thunder Wave
Considering a Ice weakness is freaking you out, with all around but in particular special bulk (as special ice is more common than physical) cresselia is awesome at taking ice as well as sponging special attacks. Also with stealth rocks up you OHKO standard DD mence with Cress' Ice Beam.
I would suggest you replace donphan as you could always use sunny day over light screen to make up for that loss and then you have phycical and special bulky sunny dayers in rotom and cress. considering that donphan isn't rapid spinning you dont loose anything by switching for cress except for power drop. also that paralysis support is vital against countering a lot of threats. Loosing reliable tyranitar counter is annoying but ape can revenge kill and if sun is somehow up tangrowth should OHKO.
