Draw supporters = Epic Fail, now that Steven's has left the format.
If you're running Claydol, unless you're really stuck for room, go 2-2. I can't tell you how many times I've played against people with their Baltoys prized. XD
IMO, in decks like Kingdra (that are relatively simple), running Claydol and Uxie is a good idea. A Roseanne's/Bebe's/Luxury Ball to search for a Uxie to get you 3-4 cards T1 can ensure that you get that early Claydol. Also, the Lv X is alright in terms of drawpower as well.
