Steel & Water Deck help please!

I have two decks, i'm not sure which to use for the Battle road thing i'm going to this weekend. I'm still sort of new to pokemon, so any advice you could give, that would help me out tons!
If you can think of other trainers or pokemon that would be better, please suggest changes for me.
Thanks! :D

Steelix/Goldeen/Magnezone, all from DP

Thank you!!

First off, I would prefer your deck over your friends be cause of the larger variety of trainers. and don't think that because it has a pokemon ex in it makes it any better. Crawdaunt ex sucks in my opinion. First thing that I would suggest is that you add a few potions to your deck. I only have onix, magnimite, and magniton but none of those pokemon look like they have attacks that heal to me. and no you will not want a discard pile of pokemon that you didn't heal. Otherwise I would add a few stadium cards(is okemon fan club one?) and your deck doesn't look that much worse. Oh, and great balls are always good to have. And only ad 2 total rainbow energys if you want them(Thank god for dark and metal basic energys:))overall I would give it a 6.5 out of ten. I would be able to rate it higher if I knew what kind of stratagy you were going for...
