SATOSHI: Hmm...not much to do here...let's get to work.
===THE POKEMON===
Okay, looks like we have a Sponge variant on our hands. And as we all know,
MP Mewtwo is everywhere. To counter this, we canneoither use our own MP
Mewtwo, Ditto, or...something else. Let's go with the later. Remove the
Areodactyl and Msyterious Fossil and add in a 3-2 Meowth-Persian line. Psy
resistance, combined with Persian's Pounce attack, adds up to a great MP
Mewtwo counter. Let's also remove the Chansey. While thy can be great
stallers, we're gonna need the spaces for Trainer aide. Add in another MP
Mewtwo, and save the other spaces for later.
===THE POKEMON===
Now, counting the Chansey and that last space from before, we have 3 spaces.
Add in another Bill and two Computer Search. Sponge relies on heavy Oaking
and searching to get that second turn 40 damage from MP Mewtwo. With the
added trainers, this should be much easier. Let's also take out a Lass and
two Energy Removal for three Gust of Wind. Make the remaining two Energy
Removal Super Energy Removal
===THE ENERGY===
Electabuzz can run on 8 Electric Energy, so let's take out 2 Electric and
add in two more DCE for Scyther and Persian.
===THE OVERALL===
Here it is:
Energy(22)
10 Psychic Energy
8 Electric Energy
4 DCE
Pokémon(20)
2 Mew
3 Mewtwo(MP)
4 Electabuzz
3 Ditto
3 Meowth
2 Perisan
3 Scyther
Trainers(18)
4 Bill
3 Professor Oak
2 Computer Search
2 Super Energy Removal
2 Lass
2 Scoop Up
3 Gust of Wind

Hope this helps!!

SATOSHI: Arcanine, come on!! Come out from under there! Errr...I'll coax him
out sooner of later...Good Luck and Happy Gaming, everyone!!
