A Set Premiere is a special event in the Trading Card Game that takes place at stores across the nation.
Set Premieres happen the weekend following a trading card game release (not including special products). These are Limited Play tournaments, using 3 (formerly 5 and 6) booster packs from the new set.
As its name implies, it is the premiere of a set, and a Set Premiere is often in Sealed format. DragonStrike Infernus was the first set to have a Set Premiere.
