Played against several LuxChomps that didn't have Dialga G LvX using a slightly different build of this deck. Every single game went almost exactly the same.
Tomb start. Evolve the Plume quickly. They pop the first Tomb, which I replace with another if Glaceon isn't already benched. They pop the first Glaceon or a Pixie, but I've already got two Glaceon in play. They take a third prize off a Pixie or a Tomb. Lock is initiated, damage limited to 60. I take 2 prizes, they take my Glaceon, I reset. I take another 2 prizes while they can no longer attack for damage without sacrificing their bench or their Energy.
Basically, they take an early 3 prize lead by taking a Tomb, a Pixie, and a base Glaceon, but then they only take 1 prize the rest of the game.
Unfortunately, Glaceon takes a LONG time to take prizes back.
Untimed, Glaceon has a distinct advantage as it's very difficult for them to take more than 4 prizes, while my consistent 70/10 will take several prizes at once late in the game.
Timed, it's virtually even because Glaceon can't take the prizes back quickly enough.
