I get these are starter decks, but oh my god. Reshiram finally gets an ex and it is slightly worse than its V, Dialga's ex is infinitely worse than its V variants, Zacian is just bad, and the Koraidon would be really good if it was classified as an Ancient Pokemon. I wouldn't even use the Blaziken ex cause Fire doesn't really have bad reacceleration right now, the only Pokemon I could think of that would benefit from it would be Armarouge ex.
Ironically the best Pokemon in these decks is probably the Lilligant since its ability brings some Grass type ex's damage to actually good metrics.
