Just an input.
With 5 pokemon with round attack, seismitoad already does 150, enough to OHKO anything not EX. Following that logic, I fail to see the need of catcher other than for destroying setup, in which case two is the max needed; in fact, even circulator may do the job just as well in getting cheap KOs. Personally, I'd rather invest in switches so you can attack with wiggly if high damage isn't needed. Besides, their retreat cost isn't exactly cheap.
Heavy ball should be replaced by pokecomm, since the only thing heavy ball can get you is seismitoad, and pokecomm can already do this AND get you the other pokemon as well. Max out rescue energy, or at least 3; you need to recycle the toads and wiggly fast, and rescue is the easiest way.
PONT is cheap, you're hardly wasting money on them. If that still doesn't convince you, try copycat or cheren instead of bianca, way better; otherwise, cheerleader. If you can't get collector, go for dual ball. All of these are really cheap alternatives that most players have spares, simply because they don't use them often in the first place.
The only real investment you may need is Pichu. At least two copies are needed in this deck for it to work. It's tougher than you think in getting out your pokemon.
On a last note, I doubt you can get out more than four lines out at one time, and I doubt you'll be ahead in prizes half the time. If you can find the space (cuz I can't), you can try black belt for getting easy prizes, or twins to help your setup. The former is bloody cheap and easily tradeable.
@Everyone above: Think you guys need to respect his decision on not getting staples. Honestly, not everyone plays to win, some people just wanna have fun, and some people don't have the luxury of spare cash. And try thinking outside the box for once, it's not that hard to build a semi-competitive engine, you know.
