Couple things I'd like to know in terms of why you run them (please don't say because it's WIND/WATER...)
Why do you run White Night Dragon, Strong Wind, Des Voltsgaph, Grunika, Dragonic Knight, and Dodger Dragon? I can think of a few options that would be better than those, like:
Koa'Ki Meiru Drago or Red-Eyes Wyvern over Strong Wind and Dodger
Masked and Dread Dragon over Grunika and Dragonic Knight
Dragon Ice over White Knight (or just none at all since the Water Suprressor isn't as useful as the others)
Exploder or Kodomo over Voltsgalph (the Earth one is one of the better ones too)
Lack of backrow destruction and staple spells is also pretty glaring. You can drop some of the suppressors for MSTs, Heavy, Dark Hole, and Reborn at least. Max out Sarco as it's a +1 (search for banishing Suppressor + Suppressor 2 turns later).
