Steelix is an okay Pokemon, certainly powerful but with drawbacks. It's rather difficult to build up Steelix (As are for other 4-energy hitters) and once Iron Tail is up, it's a risky shot. Your first flip must be a heads for it to do anything, and a second heads after that will assure a K.O. The probability of getting heads two times is rather dim.
Steelix is great as a back-up Pokemon, staller, and tanker, but focusing your deck around it isn't ideal.
If no changes have been made to the deck so far, Metagross is the main hitter. At three Energies (One must be Metal), Metagross sports 50 damage and 100 damage on recurring Extra Comet Punches after the first. Magnetic Reversal will prove any attempt to retreat in vain if a heads is flipped or you can pick off the weaker Bench Pokemon for OHKOs. It's best to supply 3 Metang, but 2 is okay if an extra Metang is unavailable.
It's okay to leave Jirachi and Farfetch'd where they are for now. Claydol
from Mysterious Treasures is an alternative to aforementioned Pokemon, and is preferable over Trainers any day.
If you choose to run an all-Metal type Deck, consider:
Special Metal Energy x4
Metal Energy x18
Or any amount of normal Metal Energies, but always include 4 Special Metal Energies. One, it couldn't hurt your deck and Farfetch'd isn't used as a hard-hitter/staller. Two, you're attaching a card that provides the same kind of Energy, just benefiting survival for Metal-types.

He needs our help to decide on Trainers, Supporters, Stadiums, and possibly Pokemon and Energy reformatting.
Team Galactic's Mars
Listed above are great Trainers/Supporters/Stadiums. Energy Link is great for transferring necessary Energies, Team Galactic's Mars beats Mom's Kindness and Buck's Training any day, and Speed Stadium is an alternative to Claydol. Sadly, I'm not the best at deciding Trainers and Supporters, but I hope my help does you some good.
