Full team I agree might be overdoing it, but I think it's perfectly valid to trade over an egg or too so you can use pokemon you would normally only get at the end of the game. This is also applicable to version exclusives as well. Personally I think Braviary is one of the coolest mons but I've not been able to use it before because I own black. Hence my Rufflet egg I have ready to go is very tempting.
