Well, actually, Warhammer made it the viable haircut first...The Mohawk is a viable dwarf haircut.
So now I have someone to blame for preventing dwarf tokens to be made way early in the game(Paraphasing) Geof Darrow's art was responsible for changing Dwarf Scouts into Goblin Scouts in Mirage

Sad truth, but it gives me hope.This doesn't mean you'll never see a dwarf again (because you will) but be aware that when you do, enjoy them as they are never going to be as plentiful as the goblins.
Again, sad truth but funny"Did you know that the game of Magic has over three hundred legends? Three hundred! You know how many goblin legends there are? Six. Elf legends? Four. Snake people legends? Seven. Seven! Golem legends? Two. Cephalid legends? Freakin' humanoid squids. Two. You know how many dwarf legends there are? One. And he didn't even hang out with the dwarves. No, the one dwarf they promote to legendary status wouldn't even give his own people two words. And even him they had to kill after one expansion. 'Cause The Man can't be havin' no dwarves in his game. At least no high profile ones anyway. And don't give me no mouth about dwarves having two legends. Balthor alive, Balthor dead doesn't count as two. Barely counts as one."
