No, currently not. The only way to make him more useful atm are +luck items/potions.
After playing a few matches with him, I think he could really use little boost per level. I know there was some sort of per level boost on the original card idea, but that was a tid bit too strong.
Do you have something specific in mind?
PS: I attached your ladder profile to your forum profile ;-)
ah thank you (whats the yellow diamond btw? ) and ill have to think about what could be done. and yeah i think the original might of been to strong (i dont remember the original tbh) but maby take the original per lvl and tweak it down?
