Caelus needs to be staff banned. He falls into the "receives most votes every week and is almost always banned" category so it would make sense. Skeelz would still have Aylen as a 5* replacement who is not as powerful, but still awesome.
I wouldn't unban any cards, since I believe that there is a reason they are banned.
Saving Ratanah would open the doors for the most OP 12/13* half deck (Yookie, Noodile, and either Arno or Rico).
