Caribou Range is a white enchant land
2WW
Enchant Land
Caribou range can only be cast on a land you control
Enchanted land has WW, Tap: put a 0/1 caribou token into play
Sacrifice a caribou token: gain one life.
Countermoose uses a card called Humility, which says that all creatures are 1/1's without abilities, to pump up the caribou tokens, and then counters most of the opponents big spells. It also runs an alladin's ring and feldon's cane for win conditions, if the caribou don't do it.
My deck was a w/g deck that brought large amounts of land into play, and spent alot of mana on cards like Caribou Range and Sacred Mesa, pumped with Glorious Anthem, and then living lands and attack.
The beauty of the deck was that, in an Alongi-esque fashion, it was based, verse by verse, on "Home on the Range"
(I wish I'd saved a copy of the decklist. Ura, if you read this, could you send me a reply that has that decklist I sent in? I may build it. It looks fun)
