With that knowledge I'm going to delete my submission post and resubmit a new deck if that's okay. I don't think many people have seen my submission yet, and the card I banned hasn't been added to the ban list on the main post yet.
Sorry for the late response!
We have no way of enforcing the ban change rule since we haven't seen it, so this will be allowed. With that said, we encourage people not to rely on this precedent, and ban choices will be locked in if we see them.
