Because of the fabrication process requirements, you will not find foiled cards within an Altered booster, instead you’ll find cards “Foiler” cards. Much like a wildcard in other games, a Foiler card is a card with a QR code which you'll scan in order to register it in your collection. Foil cards will exist in each rarity: Common, Rare, and Unique. Each Foiler can be applied to a card of the corresponding rarity that doesn't have a foiler applied to it yet. Once you use it, the Foiler is spent. When you spend a Foiler, it will apply to the card family. That means you'll only need to foil a cardname once per rarity! You’ll be able to trade Foilers over the marketplace just like other cards. When a card leaves your collection via the marketplace, the foil status is not transferred. Cardnames with Foilers applied will stay in your collection forever. If you ever reacquire that cardname at that rarity, the Foiler will still be applied! Foiler cards replace Tokens in Booster Packs 25% of the time. Foiler cards will also be a part of Organized Play rewards.
