Skarrg Goliath, Rubblebelt Maaka, and Slaughterhorn are all bloodrush cards, although not too useful.

Lightning Bolt

Kala: In the first iteration of this deck, I ran a playset of Maakas and 2 Wasteland Vipers, but I was never really impressed by them in terms of the buff they provided. I prefer the Rampagers' trample and giving +4/+4 for two mana - which I tend to have available when I have one in hand. I also like Rubblehulk, but not as much because not all of my creatures have trample without being buffed by Overwhelming Stampede or Domri's Emblem.

HydraOoze: I thought about having Bolts, but I don't know what I'd rid the deck of to have them in the mainboard. Any suggestions for them? Otherwise, they will probably sit as a sideboard option if I can't deal with some creatures in Game 1. I also used to run 2 Clan Defiance and a playset of Ground Assault to rid myself of problem creatures.

Burning-Tree Shaman deals damage to the player who controls the activated ability, so whenever you blood rush something, you take one damage. Are you using him for his big body? Or did you misread it?

ryanjoha - I am well aware of the downside to Shaman. Which is why I don't run more bloodrush cards or more planeswalkers. He is a big body that pings my opponents more than me. I also side him out before any other cards unless I need to keep bodies in (which has only happened once).
