Not a bad deck at all, just needs a medium sized tweak...

Pokémon

Your Pokémon lineup is actually fairly nice. The Rocket's Zapdos's need to go though. Drop all 3 for another Cleffa, 1 Brock's Mankey (Lv. 10) and a Ditto. Brock's Mankey helps a great deal against Slowking. Taunt it, and take it out with Steelix and Chansey. As far as the tech'ed Ditto goes, I love whipping out a Ditto late game and taking out their Sneasel. >:D By the way, make the Onix (Base) into the Southern Island Onix. The potential of 40 damage 1st turn for 2C is so godly. O_o

Energy

Since the Rocket's Zapdos's are cut, drop all 7 Lighting Energy. ALL Steel Chansey and Steelix decks should run up to 3-4 Recycle Energy, especially since we're running both. Toss in 4 Recycle Energy - they'll be Supering Chansey and Steelix like crazy to stop the destruction. Metal is VERY vulnerable to ER/SER, toss in 2 Rainbow Energy for...backup, if you will. =\
We have 1 extra slot. I'll use it for something below.

Trainers

With that extra slot, go ahead and throw in another Item Finder. Drop a Switch, EcoGym and an Energy Charge - and play 3 Super Energy Removal. Every deck in the current enviroment should be running ER and/or SER to counter Sneasel, Chansey, Steelix etc.

Ultimate Wall 1.2

3 Steelix
3 Cleffa
2 Chansey
