Aggressive Goblins. Not the most polished deck in the world, but I like it.

1 drops:

6 Multi-colour makes Jund Hackblade effective.

The Goblin Guides are Goblin Guides.

I like Wither and 2/1's for 1 mana.

2 drops:

Bloodmark Mentor; Assures me of almost constant first strike, and is handily a goblin as well

Hackblades; 3/2 with haste, what's not to like? also double boosted by boartusk

Instigators; Double Strike(good with upcoming lords)+free goblins

Rise of the Hobgoblins; With a chieftain out a lategame Rise could be devastating(if I have much land on the field), mostly used for the first strike though so I can attack recklessly or if need be defend without losing my Goblins.

3 drops:

Chieftains; Lords also give haste to any threats dropped afterwards(Boartusk Liege)

Boggart Ramgang; Haste, wither, double boosted by Boartusk...

4 drop:Boartusk Liege; Sends the green/red goblins into overdrive, Hackblades enter as 5/4s!
