Erase Anything you have 2 stacks of, Ex: Mandarin Orange, You have 2 stacks, delete one & leave the one with 99

Masamune, Medula, Legwand, Limbo stone, Sacred jewel, Royal Bud, sol creator, luna creator, Leave 1 of them for each.

Mikoruko pearl, prized cloth, divine spear, Delete them all (There are many units that give the ignore def buff)
