Burn Orb? Do you mean Flame Orb?
Why do you recommend Flame Orb at first place? This is the worst item for Stoutland since it doesn't get access to the Guts ability, to make the well known combo with Flame Orb and Facade. Otherwise Stoutland's Attack will be halved and lose HP each turn, also you don't get access to that item until you beat the game, which allows you to do Subway battles and earn BP in order to exchange for a Flame Orb and other items.
