It is pretty rare, a few packs came up for sale recently
Why Don't You Just Shoot Him?: Team Rocket would frequently try to surprise their targets in early episodes by ganging up on them with multiple Pokmon (which at the time was against the rules, which were limited to 1v1)
Werewolves were still quite strong despite its small card pool, stronger than most people gave it credit, but it lacked a key ingredient to push it over the moon
The Van Gogh Museum instituted a rule that each attendee could only receive one of these special cards by completing the museums Pokmon Adventures activity, yet some guests managed to accrue numerous cards many of which have ended up online and subjected to the collector communitys intense passion
Cards that also dump a whole bunch of lands like The Gitrog, Ravenous Ride, Worldsoul's Rage, and Icetill Explorer fit quite well with land recursion
Full arts didnt just change the cards they changed what it meant to collect them.
