Hey everybody, Skorne here.  This time around, I have a killer combination for you to try out.  Combining Southern Islands Mew and Rainbow Energy could be lethal over just a few turns.  Check out the translations for Southern Islands Mew and Rainbow Energy and you'll see what I mean (translations courtesy of Edo):
 
Mew
Type:  Basic Psychic Pokemon
LV.5, HP 30
P: Rainbow Wave
  Effect:  Choose 1 Basic Type of Energy card attached to
    this Pokemon.  This attack does 20 damage to each of your
    opponent's Pokemon that is of the same type of the Energy
    that you chose.  (Don't apply Weakness and Resistance.)
(No) Retreat
P Weakness
(No) Resistance
 
Rainbow Energy
Type:  Trainer
Effect:  This Energy card becomes a Basic Energy card of
  your choice.  When this card is attached to a Pokemon, it
  does 10 damage to that Pokemon. (Don't apply Weakness and
  Resistance).

With rainbow energy, you could specify which energy type the rainbow energy counts as, so if you're facing a rain dance deck, make it a water energy; if you're facing a wigglycrap deck, choose colorless; you get the point.  Over only a few turns, you could knock out all of your opponent's pokemon.  The 30 HP, I admit, is pretty terrible, but with some SERs and/or ERs, you should be good to go.  I can't wait to test this out at the next pokemon league. . .
 
Later,
Skorne
E-mail me at gen1551@usaor.net .  Send all the hate mail you want, wigglytuff zombies.  I enjoy reading them; I need a good laugh once in awhile.  I don't accept apprentice challenges, either, so don't bother with those.
