Recently pulled him, was wanting advice on how to gear him, whether putting him in savage or cruel effects the bomb damage, could i use him in a defense/hybrid arena team without his speed aura?

Not really considering using him for the aura, since I do not have the speed gear to make anyone fast enough, let alone Shazzy. I think my fastest champ with my best rolled gear comes out @ like 290 Speed. 

Also, is he worth building w/o booking the A3 completely? Really not wanting to book him at all.... thanks.
