This weekend will be the scheduled Iloilo Prerelease event of the latest Magic set, Fate Reforged. As per the info, Prereleases provide you with the earliest possible opportunity to play with the newest cards in Magic. The format is Sealed deck, where players are given Prerelease Packs divided by the clans of Tarkir and from that card pool they will construct a 40-card minimum deck.
