I'd imagine that it may be possible due specifically to the fact that you can increase/reduce specific skills damages on the user. Such as: Meg for Champ, the cards for: Napalm Vulcan, JT, Arrow Vulcan, Double Strafe, etc, all have increase % dmg for those skills based on a card. So assuming that it should be possible to have a card that negates the same % damage on the defendant vs. the attacker. My best logic =/
