item clause is ridiculous. there is not enough usable items in LC to make a functioning team that is not restricting. the most diverse an LC battle is going to be item wise is using three sashes in your team instead of two. most teams will consist of: focus sash, life orb, oran berry, two or three choice items, and a random stat raising berry.
having item clause doesn't help create diversity, it forces user to have a set of pokemon based on their item ( an oran user, a focus sash user, a life orb user). some teams try a stall-ish style where most of their items are oran berries, with item clause they can't use that. most teams carry two walls, both holding oran berry, with item clause you just turning it into a sweeper fest.
please reconsider removing the item clause.
