As the rules say, each character should include in their deck some cards associated with their basic habilities

C Common D/D/D Flame High King Genghis X FIRE Level 8 [ FiendFusionEffect ] ATK 2800 DEF 2400 1 Level 5 or higher "D/D" monster + 1 "D/D" monster If another "D/D" monster(s) is Normal or Special Summoned to your field while you control this monster (except during the Damage Step): You can target 1 "D/D" monster in your GY

while this card is equipped to a monster: You can send this Equip Card to the Graveyard to target 1 face-up monster you control

Magician of Dark Chaos Black Chaos would fit best in a dedicated Ritual Spellcaster deck, particularly a Dark Magicianadjacent strategy or a Spell-heavy control build that can easily recycle Spells and leverage protection for backrow (since it protects your Spells/Traps from destruction/banish effects)

C Common Crystal Blessing X SPELL Target up to 2 "Crystal Beast" monsters in your GY

The clear winner, and what I plan to use on my decks going forward, is the Perfect Fit sleeves
