I suppose you are right, but in that case, perhaps the buff should have an offensive purpose as well. I was thinking something along the lines of my Wind Aura effect, perhaps with a temporary minor attack buff to make it useful against decks that do not utilize CC, but that opens a large amount of balancing issues when one considers cards such as Dune Scorpion.
The Wind aura is a buff that negates negative effects that the creature would be affected by. Although I had it as an
ability for thematically fitting with Swift, such a thing sounds more like
, since it is essentially armor, that protects the creature. Note that while a Wind aura would protect a creature from say, Permafrost Shield's freeziing effect, it would not affect the damage resistance portion of the shield. Also, if you were to cast BB on such a creature, it would gain +0|+20, but not be delayed for 6 turns, or if you were to cast Liquid Shadow on it, it would gain Vampire, but not be posioned.
