Re: Trading for items?
I think a way to sell Pokemon would be good, but only, like, back to the mart, and for a reduced price. Just not selling them to other people, because that could be abused with unfair trades, either as a means of tricking the person, or buying a mon for $500 from someone that's leaving.
And tbh - who'd want to sell a mon for an item? Iirc, every single item is available in the mart (except Heart Scales) and not for unreasonable prices, especially since most (if not every) mons are sold for more than items.
