I'd swap the Collateral Damage for Fiery Conclusion, and swap Pia and Kiran Nalaar with Molten Vortex.

I agree that I should take out collateral damage for fiery conclusion but I really like the one mana cost. Do you think there is any way I can fit both in the deck by taking something else out?

I would replace the collateral damage with Wild Slash and maybe sideboard Fiery Impulse if there are a lot of 3-health creatures. Also Roast and Rending Volley are just straight-up value.

oops, also forgot Outnumber

I already have roast, wild slash and rending volley

I'm trying to brew something really similar too, however what i'm building will be based around Zada, Hedron Grinder and i'll probably splash white (Defiant Strike and Mighty Leap ftw). So yeah I definitely recommend him for a goblin aggro deck - it gives you that mid-game punch.

Though looking at your current deck; I suggest reducing the amount of Subterranean Scout or Mardu Scout and/or Hordeling Outburst for Goblin Rabblemaster.

Also in my opinion, Lightning Berserker is probably a better pick than Subterranean Scout.

Other suggestions I advise you to look into would be:Fiery Impulse, Sure Strike, Crumble to Dust and Firemantle Mage

I am getting a Zada soon. I really enjoy Rabblemaster but it is out of format now and I play standard. As for lightning berserker it is a great card but I prefer subterreanean scout because I can make piledriver unlockable for 2.I am starting to test with fiery impulse amd sure strike but the other cards don't really catch my eye.Thanks for the input Kewbi, I appreciate it.RdeGans

for Unblockablility, you could always use Break Through the Line.

Thanks, didn't think of that Pyro. I might try that out
