The Yu-Gi-Oh Trading Card Game’s current banlist contains over 100 banned cards alone - some cards fall into the forbidden category, while others are limited or semi-limited to retain balance. Most other major trading card games, like the Pokémon TCG or Magic: The Gathering, have set rotations, where after a certain amount of time cards from old enough sets can no longer be used in standard tournament play. Yu-Gi-Oh, on the other hand, doesn’t rotate out its cards at all. Cards released when the TCG first launched in 2002 can be used in decks with the most recently-released cards, as long as they comply with the current banlist, otherwise known as the Forbidden & Limited Lists.

For instance, fans who played in 2009 will remember the Synchro Monster Ancient Fairy Dragon not get much play, but after a few years, Field Spell Yu-Gi-Oh cards started getting stronger, and helped Ancient Fairy Dragon’s effect. Now, it’s a member of Yu-Gi-Oh’s substantial forbidden list. No set rotation makes Yu-Gi-Oh a unique game where older cards can remain relevant even after many years, but it makes its banlist crucial and extensive.
