Deck Master Format

The Deck Master Format is a modality of dueling present in Five, based on the Deck Master gimmick present in the Virtual World arc of Yu-Gi-Oh! Duel Monsters.

This modality could be present in a special event or tournament to advertise a new set of monsters, who would be used as the Deck Masters of the staff.

Rules

 * Before the start of each duel, the players must select 1 monster from their Main Deck and designate it as their Deck Master for the duel. The Deck Master card will be placed face-up in a separate slot on the field designated specifically for the Deck Master at the start of the duel.
 * Each Deck Master is designated a unique Master Effect, which is applied/can be activated for the duration of the duel, as long as it is face-up in the Deck Master slot. The Master Effect is separate from the monster's original effect, and the latter does not apply while the monster is in the Deck Master slot.
 * At any time during the duel, the player can choose to Summon his Deck Master to his field. When they do so, they move the Deck Master card from the Deck Master slot to their Monster Zone, performing a Master Summon. This Summon cannot be negated (by cards such as "Solemn Warning") or prevented (by cards such as "Vanity's Emptiness"), and no opponent card effects can be activated in response to this Summon.
 * [insert rule referring to using the Deck Master as material]
 * If a Summoned Deck Master leaves the field because of an opponent's card, its owner loses the duel.
