Sealed

From Battle Dex

Sealed is a type of game, as opposed to Constructed.

In sealed games, players are given 3 packs (opened for you) to make a deck. This gives new players who don't have many cards a good chance to play the older players who have many cards, as it levels the playing field. Since no duplicates can be in a pack, you will not have more than 3 of the same card in a sealed game, however since it is 3 separate packs, you will often get duplicates.

Sealed games are also great for mastering the technical parts of the game, such as how far away to keep units, perfecting Line of Sight, etc.
