How Sealed Works
- Choose a set and open 6 virtual Play Booster packs
- Review your card pool — sort by color, type, or rarity
- Pick your two best colors and build a focused 40-card deck
- Add basic lands to complete your mana base (typically 17 lands)
Frequently Asked Questions
How many packs do you open in MTG sealed?
In sealed, each player opens 6 booster packs and builds a 40-card minimum deck from those cards plus any number of basic lands. This gives you a pool of approximately 84 cards to build from.
How many cards should a sealed deck have?
A sealed deck is 40 cards minimum, typically built with about 23 spells (creatures, removal, combat tricks) and 17 basic lands. You can play any number of basic lands beyond what you opened.
What's the best strategy for building a sealed deck?
Sort your cards by color, identify your two strongest colors with the best removal and creatures, build a focused 2-color deck with a good mana curve (plenty of 2-3 mana cards), and include at least 2-3 removal spells.
