I think it would be fine.
White would probably have the most difficulty dealing with this.
Blue can get high flying, and bounce.
Black can get deathouch and kill spells
Red can get burn and first strike
Green can get deathtouch, fight, or out muscle it (though another green deathtouch at common seems unlikely)

Oakfist Wendigo

When ~ attacks you may untap a forest you control.
"The wendigo have been our protectors long before the starstill, and I expect them to be here long after" - Pleasenamethis guy, tribename shaman
5/5

I vote lily for using wendigo in the name.
Really though, I hope we have at least one Wendigo on the ice part.

Wizards dropped the ball when they called their yetis wiitigo. Native Americans need more shout outs.

Frostsnare Spider
Creature - Spider
Reach
Whenever ~ blocks a creature with flying, ~ gains deathtouch until end of turn.
3/5
Its web is a glittering tapestry, giving its prey one last glimpse of beauty before they enter the oblivion of death.

Apparently Wiitigo is actually another name for a wendigo (at least according to Salvation Wiki's Yeti page). I would also separate wendigo and yetis. One's a big hairy monkey, the other's a cannibal spirit.

Silver-fur Yeti
Creature - Yeti
Hexproof
4/3
For a glossy sheen impenetrable to spellery, use Shiny BrightTM Yeti Cleanser!

Flavour text subject to change.

A Wendigo should be eating something, not just a green medium-large monster. It should also be hard to kill, I think.

Relic Crusher –
Creature – Yeti (C)
Relic Crusher has trample as long as defending player controls an artifact.
5/3

That's why I made mine a spirit.

Oh yes, yeti~~~

Golden-Eyed Yeti -
Creature - Yeti
~ has hexproof as long as it is untapped.
At the beginning of each player's upkeep, untap ~.
4/5

Snowpack Wolf
Creature - Wolf
~ gets +1/+1 until the end of turn.
For many on the dark side, the moon is as if it were the sun. Its pale luminescence marks the days for some, and the meals for others.
4/4

Let's start the voting!
























I vote for Shazzeh. (Also, LilyStorm, I decided not to disqualify you, but your card doesn't fit the criterion because it costs one mana too much. Please fix that.)

Echo Robin

Echo Robin

Parad.

Vote Fakeartist, reported echo for stealing my idea from 2 rounds back.

Still the best card though
