4xMisty's Poliwag     Gym Challenge
4xMisty's Staryu      Gym Challenge

16 water energy
4 double colorless energy

3xcomputer search

3xsuper energy removal

Alright, a nice deck idea here. FTKing going on right here. Could be an interesting deck. Let me tweak it a bit.

First we have the Pokemon: Drop the Misty's Staryu, there are better FTKing Pokemon out there. Add in 3 Cleffa. This will help you in case you can't FTK, but can get some stability. The biggest problem about FTK Decks is that if they don't work they yield "a cannon-like effect". This means that they can fire one good attack, and then its hard for them to get back. So in my FTK decks, I like some stability and some strong metagame. Alright, the 3 Cleffa should help you do that. Add in 2 Ditto for anti-Sneasel, Rocket's Zapdos, etc. Add in 2 more Misty's Poliwhirl. This is a very good card especially with Water energy. Rapids is just scary with high Energy Removal, and Water Punch is beastly with Pluspowers and Mistys. And finally, drop 2 Erika's Jigglypuff for 2 Igglybuff.

Next we have the energy: Well your energy count is off, meaning you have 20. So drop 6 Water energy, and add in 3 Recycle energy. Recycle energy is a very nice card to use with Super Energy Removal, etc.

Finally, we have the Trainers: Drop the Potions, they are outdated. Drop 1 Oak, and the Bill. In my opinion, 4 Oak is too much. And Bills have been replaced by Cleffa. Add another Computer Search, 4 of this card is essential in my opinion. Add in 4 Item Finder. This card is just needed in FTK decks. Letting you pull used Pluspowers and Mistys back. Add in 3 Gold Berry, and 2 Gust of Wind. Gold Berry = your healing. Gust of Wind = your bench manipulation. Drop the Energy Removal for more room.  In this deck don't worry about a Gym, you should go for the quick win. A Stadium is needed in decks that intend to go for a longer game. So here is the deck:

Gymbo's Quick Attack
Pokemon: 16
4 Misty's Poliwag (Challenge)
3 Misty's Poliwhirl (Challenge)
3 Cleffa
2 Erika's Jigglypuff
2 Ditto
2 Igglybuff (Discovery)

Energy: 17
10 Water
4 Double Colorless
3 Recycle

Trainers: 27
4 Computer Search
4 Item Finder
4 Misty
4 Pluspower
3 Professor Oak
3 Super Energy Removal
3 Gold Berry
2 Gust of Wind

Thanks for stopping by, hope to hear from you soon!
