There was a creature in Magic: The Gathering that appeared on a handful of cards in only one expansion, then never was seen again.
As Magic Untapped has noted before, Magic has a list of creatures ranked in order of the chances of them ever appearing again. This is known as the "Beeble Scale," named after the annoying one and done creatures so hated by people that the folks at Wizards of the Coast more-or-less said that they were never coming back.
But it wasn't just the beebles this happened to. Several creatures had this happen to them. And one such creature type had a whopping four cards in total come out in their debut expansion...only to be never seen again: The noggle.
Let's go back to 2008 - a magical time where the most popular social media platform was Facebook and the Philadelphia Phillies were actually good. Eventide came out that year, too, a set rooted in Irish and Gaelic folklore.
As Magic had already introduced all of the A-list folklore creatures by this point, they had to see who was on the bench, so they chose the noggle to be on a few cards.
The noggle, a two legged dwarf/horse sort of creature, was known for it's penchant of thieving and trickery. It was based off of somewhat obscure British folklore.
However, players were not so enthusiastic about this new, odd creature type as the tricking, thieving creature type was actually found more annoying than charming. Despite WotC trying to win players over with them, the noggles just never took off and any future use was seemingly scrapped.
In 2018, MTG head designer, Mark Rosewater, actually said that, on the beeble scale, the noggle was at an 8, meaning things would have to be just right for them to ever come back again.
True to his word, the noggle has not been back since 2008. Fans still don't seem to like them to this day, and that's probably why they haven't really been seen since.
