This is my current list and so far I've not lost with it. I will explain a few things but feel free to ask any questions.

x3 Magnemite (energy search one)
x1 Cynthia (all I had)
x1 Fisherman
x2 Brigette
x2 Skyla
x3 Guzma
x3 N
x3 Professor Sycamore
x1 Field Blower
x1 rescue Stretcher
x2 Professor's Letter
x3 Choice Band
x4 Rare Candy
x4 Ultra Ball
x2 Altar of the Sunne
x3 Mt. Coronet
11x Metal Energy
Q. Why do you have 5 stadiums in the deck?
A. 3 Coronets is the minimum I would recommend because you have to have them. I put 2 Altars in there because I knew before hand that some people were going to be using fire type decks.
Q. What did you take out for the 2 extra stadiums?
A. I took 1 N and 1 Coronet out. My deck normally runs 4 Coronets.
Q. Why don't you run 4 Sycamores?
A. I replaced one with Cynthia.
The only problem I ran into during the tournament was someone made an item lock deck and they had me stalled for a very long time. I was finally able to guzma their Zoroark GX into play so that I could FINALLY evolve my magnemite into magnezone. This game ended in a draw only because I failed to look into my discard pile when I used Skyla to grab fisherman. I had one Sycamore in deck left and if I had grabbed that I'm 100% certain that I'd have won the game as I had around 10 cards left in deck and 3 of them were energies. so that tie was due to my own mistake.
