Just want to make sure I understand this correctly:
If (when?) mons like Alakazam, Ninetales, and Politoed get their hidden abilities, they will stay in NU for at least the rest of this month? That seems like a pretty baffling decision to me.
Specifically for Covert Cloak, the message that plays when a mon is sent out holding a King's Rock/Focus Band ("x flashed it's KR/FB!") would probably solve the no open sheet problem.
