This is my take at a Thunder deck. The main focus of the dek is to create a lockdown on your opponent.
Wattdragonfly is great for summoning wattail dragon fast. Wattcobra, Wattpheseant and Wattgiraffe are good attakers with even better effects. Also wattfox and battlefader can really save you in a deffensive situation. Wattkey lets wattaildragon attack your opponent diretly for huge damage. Please comment, rate and fix. :)
