Metagame

From Yu-Gi-Oh!

Metagame is the way the game is currently played in a given area. Specifically, when players talk about the metagame (or 'meta', for short), they talk about which deck styles and strategies are the most dominant in their area of play; for instance, a Chaos Deck metagame, cards that are played the most often or used by the most people, it also can mean the cards that are available in that area (through local-leagues or casual trade circles), and the current state of the Semi-Limited/Limited/Forbidden lists (If the area plays by the Traditional or Advanced Format).
