There are always going to be a few oddball Magic: The Gathering cards out there. This might be one of the game's most unusual.
It's fairly common in Magic to have cards have counters placed upon them, such as with -1/-1 counters on creatures or loyalty counters on planeswalkers. It's a handy way to keep track of certain things within the game environment.
Typically, by default, cards with counters only tend to have one type of counter to avoid confusion. That is, except that one time in 1994 where Wizards of the Coast decided to just give a card three different types of counters on it as a default option.
In that year, the expansion The Dark was released. In the set, WotC was trying to make a set with a vastly different (and, well, darker) tone. And like many early Magic expansions, there was some wonkiness as things were figured out.
But for one card, it was especially unique, and will likely never be matched in all the boxes it checked.
The card is this one - Frankenstein's Monster:
As it says: As Frankenstein’s Monster enters, exile X creature cards from your graveyard. If you can’t, put Frankenstein’s Monster into its owner’s graveyard instead of onto the battlefield. For each creature card exiled this way, Frankenstein’s Monster enters with a +2/+0, +1/+1, or +0/+2 counter on it.
First off, there was it being named directly after a literary source. While used often enough early on, in later years this was generally done away with. Even if it was public domain, Magic wanted to go the original route. So there has been a handful of these made, but not all that many since The Dark.
But what really made this one a rarity is the fact that it can use three added counters, with each creature exiled from the graveyard allowing you to choose one of them. If this is late in the game, it can be pretty powerful. But that wasn't the reason it was never done again.
Having three types of counters native to a card -- especially three types of counters that are so similar -- proved to be confusing. Simply put, it was difficult to track.
Thankfully for players, the card isn't available in too many formats as it's only legal in Legacy, Vintage, Commander, and Oathbreaker, but not much beyond that. Nevertheless it still pops out and confounds newer players here and there.
Early Magic cards tended to do that.
