Pokemon Set Legality: How Long Are They Legal In 2023

Cynthia Jul 13, 2026

Pokemon battle formats, like Standard, Expanded, and Limited, have specific lifespans. Understanding how long Pokemon sets are legal can help you prepare for upcoming tournaments and maintain a competitive edge. Let's dive into the durations of these sets and their implications.

First, it's crucial to understand that the Pokemon Trading Card Game (TCG) operates on a season-based structure. Each season introduces new sets, which contain new rules and additional cards. The duration of a set's legality often corresponds to its season.

Duration of Pokemon Sets

Generally, a Pokemon set remains legal for the entire season it's introduced. This typically lasts from February to February, aligning with the Pokemon World Championships cycle. However, this isn't always the case, and set rotations can occur mid-season, so it's essential to stay informed.

Sometimes, sets are rotated out early to balance the meta or make way for new sets. For example, the Sun & Moon series (Standard format) was rotated out in September 2021, while the corresponding seasons typically last until February the following year.

The Standard format is the most competitive and widely played format. It allows cards from the last two full seasons, along with the current season. Currently, this includes Sword & Shield and Brilliant Stars sets. Once a season completes, typically in February, its sets rotate out.

For instance, as of early 2023, the Sun & Moon series is no longer legal in the Standard format. This rotation helps keep the format fresh and balanced by removing older, potentially overpowered cards.

Expanded and Standard+ Formats

The Expanded format and Standard+ allow for even more sets. Expanded can use cards from all sets released in the current language, providing a vast card pool for players to experiment with. Meanwhile, Standard+ is a middle ground that allows cards from the last three full seasons.

These formats are popular among players who enjoy the nostalgia or the additional pacing that larger card pools provide. However, they're also more challenging to manage, with thousands of legal cards.

Once a set rotates out, it moves into the 'Retired' category. These sets are no longer legal for use in official, organized play, but fans can still enjoy them in casual games or online platforms with no official rules enforcement.

Retired sets can also make a comeback through formats like Expanded or Legacy, where older sets remain legal. Furthermore, some Retired sets may re-enter official play through special events or themes.
