I don't know why anyone hasn't noticed this, but I know what the best darn combo of Pokemon Cards is!  Aerodactyl and Mew!!  Aero stops the evolution and Mew turns lucky evos into puny Charmanders, Squirtles, or (giggling uncontrollably) Magikarps!  Combine these 2 with some powerful basics and your opponent is toast.  This archetype of deck may have trouble with a Haymaker.  A Scyther with a Slash is more than enough to down Aero.  There is one thing you can do against this.  Actually 2.  The idea is to instantly turn this decks strategy into a whole different one.  In the case of Haymaker, swith the strategy to the Kamakaze Chansies!  Build em up.  Take out that annoying Hitmonchan, Machop, Scyther, Electabuzz, Magmar, Hitmonlee or even a Machoke if your opponent slips one out there.  And don't forget the PSI Pokemon who can take out the fighting.  Mewtwos and Mews are the ideal weapons to use if that Chansey is a little hard to find. 
 
 Evolution Decks, of course, are at a big disadvantage considering the speed of Aerodactyl and the power of Mew's devo beam.  A Raindance deck can be very fast however.  In this case you call on the card drawing power of Pokemon Trader, Computer Search, and Prof Oak to find what you need and fast! 
 
 Stalls are a little problem.  Intelligent use of Mewtwo and Aerodactyl in combination with GoW will destroy that Chansey or Alakazam.
 
 Fear the new type....

 I know most people at PoJo don't like singles in decks.  The movie mewtwo and the gym mewtwo seem to work better at only one though.  This allows for more surprise when attacking with it. 
 
Nighttime Garbage Collection will be a great addition to this deck when Team Rocket comes out.  Get a Chansey, Mewtwo, Aerodactyl out of the discard pile or get some PSI and DCE energies outta there.  Or get a Chansey and 2 DCE's for Kamakaze fun!  HeHe.  Thats all for now.
