Creatures highlighted as potential blocker if it can't block

Creatures which cannot block at all (e.g. have rule on them or are decayed) or cannot block the attacker (e.g. attacker is flying but none of the defenders have reach or similar) are still highlighted as potential blockers and will still ask to declare blockers.

Would be nice for the game to at least not highlight them as able to block (e.g. decayed) or even to skip the declare blocker step.
