Best Character Cards for Cannoneer (post revamp)?

AB: 80 DEX (and pirate for the set effect)
Kaiser: 80STR that's almost 1% of my STR even it doesn't boost by %STR lines.

EDIT:

So new decks will be:
Zero, Cosair, Kanna
Jett, Xenon, Mech
DA, Hayato, BT

Anymore room for improvement?

You could switch out zero card for kaiser if you were bossing. Mine is only 40 str so it's pretty trivial. For eunwol question...maybe replace xenon like i am?
