When people say tier 1, 2 or 3 what does it mean? —This unsigned comment was made by 126.96.36.199 (talk • contribs) 18:30, December 31, 2009
Tier is an informal way of saying which decks are the most powerful right now. If a deck wins most duels, then it's Tier 1. If a deck is still competitive but doesn't win as much as Tier 1 decks, then it's Tier 2. And so on. This system changes often - usually, whenever a new set is released - and is also kinda a matter of opinion.
