Goblins are dumb.
I am playing Goblins since the Revised Edition. Even the following deck is probably sucking in Vintage (despite the 81% competitive meter!), I don't wanna play a Rakdos combo, because this deck don't understand what goblins are: "No brain, but a tribe".
Goblins are weak.
Goblins want to explain their mana base, then say "Lackey".
Goblin Lackey is probably the furiousest dork dude ever print in Mtg. That's why you see those weird Smoldering Spires and Pendelhaven (designed for elves ^^).
I play light cage, and don't need so much , therefore Strip Mine, Wasteland, Ancient Tomb, Sol Ring and Mana Crypt fit well in the deck: The 6 Goblins who cost 3 manas are , and Goblin Trashmaster is . Null Rod and Thorn of Amethyst also benefit from .
Cavern of Souls is a fantastic free counter-counterspell, in a format where they proliferate.
Goblins are ugly.
Goblin Berserker says:
Goblins don't know the meaning of the word "tactics" — or the word "meaning", for that matter.
Matchups & Sideboarding
Obviously this cheap deck vintage can't really afford to face the Meta. The number in brackets refers to the number of sided cards.
BUG (2)
We have a small chance against BUG, so we have a slight siding.
Out: 1x Chalice of the Void, 1x Null Rod
In: 1x Pyroblast, 1x Red Elemental Blast
Golos Stax (5)
Our artifact hate 3x Goblin Trashmaster and 1x Null Rod aren't enough, and we may be slowed down hard by the cage. Furthermore, The Tabernacle at Pendrell Vale is really punishing us.
Out: 2x Legion Warboss, 1x Goblin Piledriver, 1x Battle Cry Goblin, 1x Thorn of Amethyst
In: 2x Blood Moon, 2x Goblin Cratermaker, 1x Null Rod
Dredge (6)
The matchup is terrible.

Oath of Druids (6)
Should be adjusted according to variants.
