I'll agree with Jake on taking out the cleric and the bard. Sideboarding the cleric might work really well against aggro, so keep that an option. Definitely focus more on cascading into allies and you could be into a really intense aggro ally build.
I would say -3 Ondu Cleric (move to sideboard), -2 Makindi Shieldmate, -2 Joraga Bard, -4 Harrow, -2 Captured Sunlight, -2 Turntimber Ranger
+4 Bloodbraid Elf, +1 Violent Outburst, +1 Kazuul Warlord, +4 Lightning Bolt, +3 Garruk, +2 Sarkhon Vol
