Are people still considering Carbink a capture option? It's literally showing up two episodes before the league begins, has no merchandise to support it (read as: like pretty much every Pokemon that isn't Pappatoad) and is pretty much confirmed to not happen due to the mention of Ash's sixth Pokemon 'Arriving', which it can't do if Ewwby Carbuncle is going to be captured and taken with him.
