Metagame refers to the Deck(s) in current competitive use that are having the greatest success. 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. Typically, as metagame Decks become more common, Anti-Meta Decks appear in order to counter them. The current most common Anti-Meta Deck is "T.G.". Anti-Meta Decks are generally not very versatile, so while they may be strong against one type of meta Deck, they may also be much weaker against another type of meta deck.
The current Decks that have been recently placing high in tournaments include: "Dino Rabbit", "G.A.M.", "Fire Fist" and "Wind-Up". Other notable Decks also include: "Six Samurai", "Dark World", "HERO", "Gravekeeper's", "Chaos Dragon", "Geargia", "Inzektor".
