It's titled Gruulggro, not GruulAggro. It should be near the top of this subforum. Possibly, it was moved to one of the higher tiered forums in standard like "Established". Last time I checked, it was still under the deck creation forum as of a day or two ago.

Domri, City Smasher is not good.
Zhur-Taa Goblin in place of an Instigator or Ironshell.
Kraul Harpooner is a decent 2 cmc 3/2 with reach to replace ironshell or Instigator.
Collision // Colossus for either buff or annoying big flyers (Shalai, Voice of Plenty)
Rhythm of the Wild would be better here than Burn Bright. Creatures can't be countered/haste.
Charging War Boar for Gruul Spellbreaker.
Lava Coil is always a good removal.
