One Deck

Rules

A One Deck game works like a normal game except that every player draws from a common library and uses a common graveyard. Use the following rules when playing this variant:

 Deck Construction

You should build a 120-card deck for a four-player game. Add at least twenty cards for each additional player. Decks for One Deck games typically use all five colors, but you can build a deck using fewer colors if you want. Avoid using spells that require two mana of the same color in their casting cost or activation costs; that way each player will have a better chance of being able to play the cards he draws. You should also reduce the number of one- and two-mana spells. Such cards are usually good only in the early game, and it may take a while to get even one land of a particular color.

Banned & Restricted List

When playing this variant it is usually decided what Type you will be playing. So, if you are playing Type 1, Type 1.5, Type 2, or Extended One Deck then, follow that format’s Banned and Restricted List.

Mulligan Rules

Standard “Paris” Mulligan is used for this variant.

Before each game begins, a player may, for any reason, reshuffle and redraw his hand, drawing one less card. This may be repeated as often as the player wishes, until he has no cards left in his hand. After the participant, who plays first, mulligans as often as he likes, the decision of whether to mulligan passes to the other player. Once a player passes the opportunity to mulligan, that player may not change his mind.
