This is one of the two main '3 ofs' of an Egyptian God Deck, and one half of the 'Immortal God' strategy
You can obtain the Dusknoir (3-Diamonds rarity) card by opening Mega Rising: Mega Blaziken from Mega Rising set

Decks in the game are built upon the principles of various colors (supposedly representing martial arts styles: Red - a more energy heavy attack style, Blue - a more defensive fighting style, Orange - tends to focus on allies, drills, and setups, and Black - which has a large amount of board manipulation), races (Saiyan - which is primarily a physical combat style and Namekian which focused on deck regeneration and manipulating the discard pile), or "Freestyle" cards, which represent no specific style, but can be interjected into a deck regardless of Tokui-Waza
You can only use each effect of "Solfachord Solfegia" once per turn
Opposites attract when you fuse Fire and Water types, offering two paths to victory
