I think you want a rock resist, otherwise CBTar / Jolly DDtar will rape this.Something simple like changing your Suicune (there's a reason this has declined in use this gen) to a standard Mixpert will help this team a lot.
After that I'd probably eliminate Calm Mind from 3 of the 4 Pokemon that use it, lol. Rest-Talk on Cressy, or AT on Bliss is preferred.
Deoxys-e as a purely special sweeper seems like a waste , and you've already got your solid mixed sweeper in Infernape. Pick one or the other, and replace the one you don't use with another stall-ish Pokemon. Something with Rapid Spin preferably.
To be honest I'd just ditch the concept of stat raising on this team all together (other than maybe your infernape/deo). If you play with stall, you're going to find the most success by using as many defensive/support moves as possible, not just randomly raising your stats. If you want to threaten your opponent with high powered assaults, run a sweeper team. If you're seeking a middle ground, run a good mix of both types of Pokemon, and use them for their intended purposes.
I'm going to leave it at that because I'm more or less just giving you general advice about Pokemon, and just reconstructing your entire team.
