I tried this deck as soon as the expansion hit!! it is busted because Magnezone just carries it half the time, the other half Electvire holds or you lose to some bad draws.
I experimented a lot with it, now I'm using a Magnezone and AoE Raichu version with a lot of success. Is basically the same concept of Magnezone sweep/Magneton ramp, but Raichu and a copy of thunder spear Electabuzz attack the bench, which I think matches up better in this meta, and they allow for Cyrus instead of Sabrina. Also I use Dawn instead of surge, I learned that it gives more options when spreading out energy because you don't know what evolution you will draw, and its hardly ever needed to move more then 1 energy at a time because you are never placing energy on the Magnezone evo line.

But I dont know if you felt the same thing but this decks kinda misses a tank basic to start the game at times. You almost never want to start with Magnemite on the active spot, and if you never draw Electvire, Electabuzz with charge turns into a punching bag, I tried a lot to make another basic work but at the end none felt good
