Duality Monsters

The Duality Monsters (二元性モンスター Nigensei Monsutā) are a new mechanic created by LHK. They are colored black and white (half and half), and they reside in the Extra Deck. Much like what s and s do, Duality Monsters need a Merger monster to Summon. Duality Monsters have a Chaos Count, a grey and light-blue-colored indicator, similar to the Cost Count of the Escalation Monsters, which shows how many monsters your Graveyard must have to perform a Duality Summon (e.g. to Summon a Duality Monster with a Chaos Count of 8, you need to have 8 or less monsters in your Graveyard to perform that Summon). To Duality Summon, you need to banish a Merger monster, listed on that monster's text, and banish a monster from your Graveyard whose Attribute is the "opposite" of that monster, as shown in this chart:
