Chargin Goblins

Enchant Mountain
Enchanted land can't be tapped for mana and has
"{b/r}{b/r}, {t}: Sacrifice any number of goblins you control, then charging goblins deals damage to target player equal to the number of goblins sacrificed this way."
and "{ut}: For each goblin you control you may create a 1/1 red Goblin token with haste.".
From the mines to the battlefield they come as an avalanche of violance and viciousness.
