>>37855999 said, getting ahold of an Odd Keystones isn't even the hard part. You NEED to talk to players 32 times in the underground in order for the Spiritomb event to trigger (placing the Odd Keystone in its tower isn't enough) so people who didn't have access to a second DS and another cartridge of D/P/Pt where basically fucked.
Other than that, I guess it was kind of tedious when you did it by yourself since you had to talk to player, go to secret base, leave secret base, talk to player...32 times (that's how I did it back then - snag siblings cartridge and console and just get this shit over with) but I'd say that's still nothing compared to hunting down a Feebas field back in gen3.
Currently it's probably Glameow.
