I've seen many people trying to combine Sponge/Bungee decks with Wigglytuff decks, but the trick isn't in using every pokemon that both uses, but instead figuring out what can be trimmed. As we look at the Pokemon before us... Mewtwo, Electabuzz, Scyther, Wigglytuff... what pokemon will best work in our deck? Personally, I see Mewtwo, Electabuzz, and Wigglytuff as being the best... though some prefer to use Mewtwo, Scyther, Wigglytuff. You could use either, just making the appropriate energy changes and minor trainer changes from those I'm going to recommend to you now. WARNING: This deck is *VERY* tight. You will need lots of practice to play a deck like this if you want to make it effective.

Pokemon (9 Basic + 3 Evols = 12 Total):
3 Mewtwo
3 Electabuzz
3 Jigglypuff
3 Wigglytuff

Energy also must remain tight.

Energy (13 Basic + 4 Special = 17 Total):
5 Electric
8 Psychic
4 Double Colorless Energy

Now we will load up on trainers to try to compensate for the low number of Pokemon and Energy.

Trainers (31 Total):
4 Bill
4 Professor Oak
3 Computer Search
3 Gust of Wind
4 Nightly Garbage Run
3 Energy Removal
3 Energy Retrieval
4 Plus Power
3 Item Finder
