I love messing around with handbuff decks and yours seems to be pretty solid. Nice job.
I took your list and thought I'd throw it on its head a little bit and change the mechanics to a healbuff.

I almost never use Blackguard but they can do some serious damage in this deck and become immediate must-removals for your opponent. Anyway, your deck is certainly more built for climbing and real competition, but if you want to try a fun variant in casual my version is pretty fun.
