I've been finding Belial very useful, 4 damage to the face with the option of a board wipe and whatnot, but if he's not working for you for whatever reason then cut away.

Valefar doesn't really do anything that Asmodai doesn't, especially since there's only a small handful of cards that can't hit 3k defense, so maxing Paimon would be better if you're cutting Ayporos IMO.

Personally I've found Beleth rather weak, his small stats can make it hard for his high critical to actually hit, and you tend to take a lot more damage the turn after playing him due to his low defense.

I'm surprised Abra is failing you, spells are your opponent's main line of defense in this game. Are you having gauge troubles, or are your opponents just not using their spells well?
