I've become a huge fan of CBChomp. I used ScarfChomp for a little while, but honestly, about 90% of the time the Scarf was just a liability, since people would usually switch to something slower.
I, like I think it was Hyra, run both Outrage and Dragon Claw, just because I got sick of having to use Crunch/ Stone Edge when I knew a Levitater was coming in, but didn't want to go into an Outrage just yet.
If your team has pretty good paralysis support and you can manage to get your opponent's Steel type to about 40%, you can just demolish semi-late game with CBOutrage, which is pretty cool, and till then you can smack things with Dragon Claw and Earthquake
I used a Yache Berry Garchomp on my last team, and it also worked really well, since pretty much every team counters chomp with either Cresselia or like an Ice Fang Hippowdon, so you can either get two SDs, or if your counter is at semi-low health, you can stick to one SD and KO Weaviles/ Mamoswines / Starmies while they Ice Shard / Punch / Beam
