The cookie hat had +50 stats only for the Christmas Season. Got nuked and got replaced by the NYH. But meh, enough about that.
I like my Sun/Moon, but it irritates me that I have to own 4 pieces of kiels just to have a full set. 2 for the helm, 1 for the Sun and 1 for the Moon. I hate to decard since it is a waste of money and time. If I had an F. Soldier and a Rucksack, I'd be saving a skill slot and an F. Helm. Sun/Moon is convenient, but not so much. If the Sun/Moon had an auto Maya P effect, then I'd be happier. The Maya P card is worth 1 coupon anyway and cheap like GR.
