I recently played in a tournament in Fort Collins Colorado at Marshaks
House of Fantisy. I Thought it was going to be easy with 28 people showing
up at the last one. When I got there 58 people already showed up. At the
end there ended up to be 88 people there. I lost two out of 8 matches due
to that all the decks I fought were Haymakers and I play a colerless deck.
My deck encludes

4 Jigglypuffs for it's lulaby attack
3 Wigglytuffs for it's Do the Wave that dishes out mondo damage
4 Dratinis even though theyb stink Dragonair dosent
4 Dragonairs Hyper beam is the best attack in pokemon right now
2 Clefaires metronome of course
2 Clefables for a H.P. boost on clefairy
2 Kangaskahns for 90 H.P. and comet punch

1 Computer search
