This is a deck that I like to call Wartortle's Supper. I've been working on this deck for a while.
Well here it is:


Wartortle¹s Supper v3.0

4x Squirtle (Here for Wartortle)
3x Wartortle (The Suppa Man)
3x Tentacool (Bad Basic. Here for Tentacreul)
2x Tentacreul (Auto poison and possible confusion)
3x Lickitung (Staller. Stall till everyone's pumped)
3x Koffing (Double-edged sword. Confusion or poison.)
2x Team Rocket¹s Oddish (Auto sleep or auto poison. Which do you go? Depends on the situation)

10x Water Energy
8x Plant Energy
3x Double Colorless

2x Energy Search
3x Bill
3x PlusPower
3x Gust of Wind
2x Lass
3x Goop Gas Attack
3x Smash!Challenge Form

The stratedgy is to stall with Lickitung till you can get a pumped Wartortle out and then its Suppa Time!!! If you have to fight with Squirtle. Try to paralyze. Next turn evolve into Wartortle, lay a D.C.E. and Bite. Look for status effects with Tentecreul, Lickitung, Koffing, and TR¹s Oddish.
Wartortle should be able to take out fire guys ands the other guys are there for support. If you can and want to get it over with and get a good hand you can get a second turn Wartortle Biting away at their HP.
