In the second example deck (3 Moe + 2 Sexy), why choosing Sexy cards as filler? Assuming that an offensive Moe deck should be attacked by Sexy decks mostly, then using Sexy cards as filler won't add anything to that matchup. Shouldn't be better to fill with Babe cards instead?

Maybe I'm missing something, or maybe I didn't get the Moe v/s Babe v/s Sexy specific advantages, but If a Moe Deck attacks a full Babe deck, adding Sexy cards should give an advantage to the opponent deck. And if that same Moe deck gets attacked by a full Sexy deck, then having other Sexy cards would cause a match only based on lvl.
Filling the Moe deck with Babe cards wouldn't cause any advantage on the offensive, though, but at least won't give a disadvantage, and should give better chances when defending, too.

Please correct me if I'm missing something, I'm starting to get confused xD
