Strategy Overview
Blastoise is really useful in UU and should be kept alive as long as possible to keep dangerous Pokemon like Nidoking and Sandslash from sweeping your team. Wish support is not a bad idea, but is hard to pull off, so if you're really insecure about keeping his HP stable I recommend you use Sleep Talk. The longer Blastoise lasts, the more time your other Pokemon have to find a hole in your opponent's team. You would probably use him like you would use your bulky Water-type in standard play.
