Kalon holds the record for highest BB atk boost without using UBB. 450% with SP. 650% with UBB and SP.

Also, since you can't get Neferet, which can do 450% with BB and SBB (no UBB boost) but can't be SP improved, Kalon is the best choice.

His seven star does do a little less than Neferet's seven star, but he makes up for it by boosting attack in general and also increasing elemental damage.

Lauda also does 500% with UBB and Kalon does 450%, but again, the other attack bonuses make up for it. His OE is close to Kalon's but still not quite.

Sirius just stinks with BB boost when comparing their seven stars. OE is just under Kalon's OE as well.

I actually think they may work together well when you ignore the BB buff clashing. Kalon's spark enhancements and good timing will be pretty good, but I'm kind of a noob with spark knowledge so I'm not sure.
