Balanced and Unbalanced Metagames: A Look Back at the Formats We've Covered

Introduction

Hello everyone,
This is the Showdown Tier team.

Showdown Tier is a web platform dedicated to statistical analysis of the Pokémon metagame.

Although the site itself is still relatively new, having launched in October 2025, we have already analyzed seven different formats. Some of those formats have developed into healthy, well-balanced metagames, while others have been far more warped. In this column, we'll look back at the formats we've covered so far and examine what balanced and unbalanced environments actually look like through Showdown Tier's data.

How We Think About Metagame Balance

In Showdown Tier's analysis system, a Pokémon that posts both dominant usage and overwhelming win-rate performance—enough to clearly distort the competitive landscape—is categorized as Tier S. When a Tier S Pokémon exists in a format, we consider that a sign of an unhealthy metagame.

Pokémon that fall short of that extreme, but still combine metagame-defining usage with strong win-rate performance, are categorized as Tier A. A format with Tier A Pokémon is not necessarily unhealthy, but because these Pokémon tend to shape team building and appear heavily at higher levels of play, such a metagame is often somewhat skewed.

On the other hand, when there are no Tier S or Tier A Pokémon, and the highest-ranked group is Tier B, we view that as evidence of a balanced format. In those environments, no single Pokémon stands out too sharply in either usage or win rate, and a wider range of viable options can thrive.

With that framework in place, let's move on to some concrete examples.

OU

Among all the formats we've tracked since the launch of this site, OU has consistently remained the most balanced. We believe this is a strong reflection of the Smogon community's continued efforts to keep the format in check through ongoing metagame management and tiering decisions.

In fact, throughout the entire period we've analyzed OU, not only have Tier S Pokémon failed to emerge, but even Tier A Pokémon have been extremely rare.

As of April 2026, the OU metagame has no Tier S or Tier A Pokémon at all, while multiple Pokémon sit in Tier B, including Great Tusk, Kingambit, Gholdengo, Raging Bolt, Zamazenta-*, Kyurem, and Iron Treads, among others.

Below them is a pool of more than twenty Tier C Pokémon. That tells us something important: there is no single Pokémon with clearly overwhelming influence, and a wide variety of Pokémon are able to find success in the metagame. Taken together, that makes OU a very healthy and impressively balanced format.

Next, let's look at what is currently the most popular doubles environment on Showdown as of April 2026.

VGC 2026 Regulation F

The current official VGC ruleset, Regulation F, is not quite as balanced as OU, but we still consider it a relatively healthy format overall.

Urshifu, Flutter Mane, and Incineroar are frequently evaluated as Tier A. They appear on a large number of teams and clearly play a major role in defining the format, but their win rates remain only moderately high rather than truly overwhelming. In other words, they are undeniably strong, but not so dominant that they push the metagame into Tier S territory.

Because this format has been studied and refined by players for such a long time, its major archetypes have become fairly established. Even so, the format has avoided collapsing into an unhealthy state, which suggests that the official Pokémon rules have been balanced quite well.

Of course, that is not something VGC can always take for granted. In past eras, there have been official formats that were far more centralized and far less healthy.

What Does an Unbalanced Format Look Like?

There have probably been many unbalanced formats throughout Pokémon's competitive history. However, among the formats Showdown Tier has analyzed so far, the clearest example of an unbalanced metagame has been the following:

Terastal Crescendo

Online tournament rulesets with especially heavy restrictions often tend to produce more polarized metagames, and Terastal Crescendo was a textbook example.

In this format, Miraidon reached over 60% usage while maintaining a win rate close to 52%, and the metagame was effectively built around it.

At the same time, Iron Bundle, one of the few Pokémon that could apply strong pressure to Miraidon, posted over 20% usage and a win rate above 55%. That alone says a great deal about how heavily skewed the format had become.

That said, an unbalanced format is not automatically a bad one. In a short-lived setting such as an online tournament, a heavily warped metagame can sometimes be exciting precisely because of how extreme it is. Of course, if an official long-term VGC format were to become that unbalanced, it would be much harder to view positively.

Our goal here is simply to show, through Showdown Tier's framework, what a clearly broken metagame looks like in practice.

Closing Thoughts

The release of Pokémon Champions is now just around the corner on April 8, 2026. We hope its official format develops into a fun, healthy, and well-balanced metagame.
