Pokemon Breeder has got to be one of the most uniquely useful and deck saving 
trainers.  Hold on a minute, what is that you say?  A trainer? They are 
useless without the right pokemon.  Well, this is true.. HOWEVER, consider 
building a deck with them as just a.. a convenience.  Well, it can be saving, 
supposing you have that blastoise in your hand, and the squirtle on the 
bench, but can't draw one of your 2 wartortles.  Supposing you have an 
overgrowth deck with weedles, 2 kakuna's, and 2 beedrils, as well as 
squirtles, 2 wartortles, and 1 or 2 blastoises.  In that you have 4 stage 2 
evolution cards, but they can be mis-matched, you can end up with 2 kakunas 
when you need that wartortle most.  Well, making a deck without 1st stage 
evolutions, or with one or two lines without them, and adding in 4 breeders.  
This gives you 4 wild card 1st stage evolution "pokemon" in your deck, 
assuming you have the 2nd stage.  Computer searches, Pokemon Traders, Bill's, 
Pokedex's, Pokeball's, and professor oaks can all help you get your holofoil 
cards in your hands.  Its a tip that has paid off for me very well, and 
sometimes free's up 4 cards, for that chansey you always wanted to stall 
with, or even to stick in a couple abra's and alakazams (without the 
energies), to sit back and damage swap your pokemon while you blast em with 
the big boys.  The same card can be used to evolve every single one of your 
pokemon, quickly to second stage. Truly powerful.
