Help! Stop! Thief

I was playing Pokemon Mystery Dungeon Explorers of Sky and thought about how OP Kecleon was in the game. I decided to look up the card and realized that there is a bit of a gimmick to it! If you are able to become any type using the ability, then you can become the weakness of any opponent. Then with Kabutops, do 4x damage to your opponent, resulting in 360 damage! Now I realize this deck isn't foolproof cause with many Pokemon, you can easily dissect and destroy the deck. But it is a lot of fun. If you have any opinions to help change it or make it better, comment and let me know! It was just fun to make.
