How Disney Lorcana Prerelease works

You are provided with six booster packs to use as your individual card pool, from which you build a 40-card deck using any number of different inks (rather than only two inks). You'll open 72 cards in total across your six packs, select at least 40 of them to build your deck, and then get paired up and play games against opponents who have also built Prerelease decks in swiss-style tournament rounds (there will be a maximum of 4 rounds in total).

Decks in Prerelease must contain at least 40 cards, however there is no maximum deck size and you may use as many ink colours in your deck as you like. Prerelease decks may contain any number of copies of any individual card. For example, if a player opens six copies of Genie– The Ever Impressive, they may play all six in their deck. Everyone that plays in the event receives at least 2 additional boosters just for playing, for a total of 8 boosters. We will play up to 3 rounds, but you get 2 boosters if you finish just one game!
