■General Information
Swiss Round only
At the Duo Standard, players will prepare two standard decks.
There is no sideboarding between games, but we also prepare sideboards (for cards like 《Mastermind's Acquisition》).
The deck you use can be two different decks, even two decks of the same archetypes with different adoption cards, even two exactly the same decks.
A match is made by each player using two decks as follows.
First game
· Either player uses one of the two decks. We decide play first at random.
Second game
· The second game uses the deck of one who did not use each player with the first game.
· Players who were drow first in the first game will become play first.
Third game (if needed)
· In the third game, each player selects one of the two decks for use.
· We decide play first randomly.
