Changes

The [[Dark Synchro Monsters|Dark Synchro]] and [[Dark Tuner Monsters|Dark Tuner monsters]] are exclusive to the Dark Signers. Dark Synchro Monsters are [[Synchro Summon]]ed by sending to the [[Graveyard]] 1 [[Dark Tuner Monsters|Dark Tuner monster]] and 1 non-[[Dark Tuner Monsters|Dark Tuner Monster]]. The non-[[Dark Tuner Monsters|Dark Tuner Monster's]] [[Level]] minus the [[Dark Tuner Monsters|Dark Tuner Monster's]] [[Level]] must be equal to the Dark Synchro Monster's [[Level]], which is [[Negative Level|negative]]. Currently Negative Levels do not exist in the real life card game.
