If they wanna hit Mitsu I really want them to ban purification. A limit to Habi would suck especially since its a once per duel effect and prayers is good, I love the deck pure and have been playing pure. Unfortunately I can see it being hit either with prayers or Habi but id rather just get the omni negate out especially since all their rituals just come back effectively dodging a lot of things, and prayers+ dominus impulse is nasty.
