Hereunder are the metagame snapshots and diversity numbers for the previous months for Standard, UU, Uber and Suspect ladders(where applicable).

Since I'm issuing these for the first time, a quick note on how these work is in order.

What I call a **metagame snapshot** is a list of Pokemon that are typically used in that metagame. Not all these Pokemon are used equally, however. They are listed in five lines. Two, three, four, five and six of the Pokemon listed up to the first, second, third, fourth and fifth line respectively are typically used in a team for that metagame.

The **diversity numbers** are just the number of Pokemon in each line, and finally their sum.
