Hard hitting decks, preferable with a Stage 2 main attacker. Attack being the best form of defense in my opinion. Don't ask why it has to be a stage 2 main attacker, but it just always ends up that way. And the decks never seem to have any major snipping ability either, or if it does, it's only to make the targeted Pokémon active, so they always do a large amount of damage to the active.
Sorry to go off topic, but SA667, if Dugtrio was never a good card, then I don't why Bastiodon will be better.
