OS Repack Draft with Ante is a Booster Draft format. Players will play with repacked boosters, including custom proxy cards chosen from the poolset of Old School legal cards (see the list of supported sets).

In addition, each booster will include at least a Card with Ante that players can feature in their decks. These special cards allow the winning players to "steal" a single card from the deck of their opponents at the end of each game. These cards can then be added and used by the winning players in later games. Therefore, players will agree on their respective ante card at the beginning of each match!

Draft Rules Description:

Players are seated randomly at the table. Once everyone has found their seats, each player opens their first pack, chooses one card from the pack, and puts it face-down on the table. Once done, pass the rest of the pack to the player on your left. Once everyone has passed their packs, you pick up the next pack (located on your right), pick the best card for your deck from that pack put it in your pile, and again pass it to the neighbor on your right. This process continues until all the cards from the pack have been picked.

You then get a review period to look at the cards you have picked and figure out what direction your deck is going. Then you can build your deck, adding as much basic land cards you want to your deck, and require that the deck be at least 40 cards. The standard number of lands in a draft deck is 17–18.
