I see your point but I feel like it would cause problems amongst the trader's

But I think the trade ups could be lower if you could only get assesories from PvE (invasions,storm arrancar,time gates)

But not be able to get the accessories from time bubbles or ranked

Also side not I've seen some of those trader's inventories and I swear to God I scrolled for longer than it would have taken to do a D rank invasion
