Why should the sacrificed creatures be white? I think this should read:
General Barntosser

Legendary Creature -- Human Soldier
2/2

, Sacrifice two creatures: Counter target noncreature spell unless its controller sacrifices a creature.

, Sacrifice two creatures: Remove tareget nonland permanent from the game unless its controller sacrifices a creature.
Those abilities should include a mana cost, I think. Also, the second ability doesn't need "non-creature".
