Plasma Frigate only takes off the weakness if they have plasma energy attached. So its okay, not great. I would also suggest a few plasma badges for pokemon that are not team plasma. As good as they are i would probably suggest getting rid of the hypnotoxic lasers for plasma badges if you plan on abusing glaceon's ability. Though i'll from personal experience, i never find vaporeon all that useful especially since you are already running anti ex jolteon. I would rather use leafeon to counter keldo decks, would ruin this deck simply because it could walk over you since you have no grass types and jolteon would only stop it from attacking if it doesnt switch out and rush back in. Though thats just my what i've seen from battling my roommate with my keldeo deck.
