SEALED DECK FORMAT
This is a great format if you look forward to the excitement of checking out new cards and playing without being required to bring your own pre-built deck.
Unlike constructed games—where you arrive with your strategically created deck—in a sealed deck tournament, you build a new deck from six unopened booster packs at the start of the event.
The guidelines require that you build a minimum deck size of 40 cards, but you can add as many basic lands (Plains, Islands, Swamps, Mountains, and Forests) as you’d like, even if they weren’t in the booster packs you opened.
If you're looking for a fun way to boost the size of your card collection while playing the game, sealed deck is the way to go.
