I've been testing a version of Goblins on Cockatrice that has had some exciting and very good results:
The Horde
Mana (21):
4 Cavern of Souls
4 Bloodstained Mire
3 Badlands
3 Mountain
4 Wasteland
1 Strip Mine
1 Black Lotus
1 Mox Ruby
Dudes (32):
3 Skirk Prospector
4 Goblin Lackey
4 Goblin Warchief
1 Goblin Chieftan
4 Goblin Ringleader
4 Mogg War Marshall
1 Siege Gang Commander
1 Kiki Jiki Mirror Breaker
1 Goblin Sharpshooter
4 Goblin Matron
1 Krenko, Mob Boss
4 Earwig Squad
Prison (7):
4 Chalice of the Void
3 Null Rod
Sideboard:
4 Ingot Chewer
4 Shattering Spree
4 Grafdigger's Cage
3 Goblin Bombardment
Skirk Prospector is absolutely nuts, it comboes with the token makers to ramp you ahead on mana. Kiki Jiki is there for value plays: copying Matron for a tutor effect, Siege Gang to amass an army, the possibilities are endless!
As for the board, Bombardment has been pretty sweet against Oath and Dredge and the creature matchups.
Workshops is usually a bye in that you amass a ton of board presence via your token makers.
What are everyone's thoughts?
I'm planning to take this list to a local Vintage tourney in a couple of weeks. The tourney was set up for testing for Eternal Weekend. I plan to test the following changes:
-1 Black Lotus, -1 Mox Ruby, +2 Simian Spirit Guide
-1 Ringleader, +1 Stingscourger
The unpowered changes are preference only. I have access to power for the tournament but would rather see how far I can get without it ($400 on the line for unpowered first =P). The other change is purely from my experience playing Legacy Goblins... never leave home without a Stingscourger in your 75.
