I have a Yun deck that has Hades Cannon as one of its primary kill cards. What with it going away once rotation hits, I wonder if there are any other cards out there with the same (or at least similar) effects. Its ability (paraphrased) is
E: Whenever you gain vitality during this attacks enhance step, this attack gains that much damage instead.
Is there currently anything that'll survive rotation with that ability? Thanks, guys!
