The Judo strategy, which uses your opponent's own Pokémon against 
him or her, using such moves as Metronome, Mirror Move, and of course 
Transform!  This would have to include some of the following:
(1) CLEFAIRY (rare Base):  Obviously for Metronome.
(2) GASTLY (common Base):  Destiny Bond.
(3) IMPOSTER PROF. OAK (rare Base):  A classic strategy foiler.
(4) PIDGEY (common Base):  See Pidgeotto.
(5) PIDGEOTTO (rare Base):  Mirror Move, obviously.
(6) MEWTWO (rare Base):  Psychic for heavy Energy Pokémon.
(7) SPEAROW (common Jungle):  More Mirror Move.
(8) CLEFABLE (rare Jungle):  More Metronome!
(9) GENGAR (rare Fossil):  "Curse" - the anti-Alakazam! (Pokémon Power:  
Moves one damage counter on an opponent's side.)
... and do I even have to list it??
(10) DITTO (rare Fossil):  Transformation.  There are few cards with 
Resistance to their own color, right?
And perhaps...
(11) MEW (rare Fossil):  "Psycho Wave", same as Mewtwo's Psychic, and 
"Degenerate Beam", for temporary fix of massively Evolved Pokémon.
