I've got a few ideas for you.  First, you might want to add fighting pokemon 
like hitmonchan.  This will end your problems with colorless that resist your 
psychic pokemon.  Those colorless are weak to Hitmonchan, and he's AWESOME.  
Take out Gastly/Haunter and Drowzee.  They aren't good at all.  Add more Jynx 
and maybe another Mewtwo.  Rattata/Ratticate is too weak to play.  Remove 
them, and add more Farfetch'd.  Farfetch'd has resistance to fighting, which 
makes him very good.  You might want to take Dratini/Dragonair out and add 2 
Chanseys.  He's a HUGE basic that has great moves.  Try running 4 Bills and 2 
or 3 Oaks.  They will increase your chances of drawing what you need.  The 
Potion, Super Potion, and Defender can all be dropped.  They don't really 
help your deck.  Add more Gusts and more Switches instead.  Also, you need 
some Double Colorless Energy for your Farfetch'd and Chanseys.  Once you get 
some good fighting pokemon like Hitmonchan to take colorless out, you'll have 
a very good deck.
