I’m sure I already know the answer but figured I’d ask just to be sure …. Is there a way to revert an unlocked battle opponent back to its item?

I am thinking of collecting the ‘legendary tracks’ items and it looks like I’ve already unlocked two of the hidden challengers in the past

I assume once an opponent is unlocked there is no way to get the item back, Is that correct?

Thank you

yeah, the summon is one-use, one-way-only, you'd need to buy a second in order to get the item again
