Dear Pojo,
I havea question. It will be more clear if I provide it with an example.
I have a Nidoran Male as my active pokemon. Can I set down a Pokemon Breeder, use Oak, and if I get a Nidoking play it directly down on Nidoran?

Nope.  You have to play the Nidoking when you play the Breeder.  It's an immediate evolve thing.
