Patchwork
If you activate "Polymerization" you can use 2 monsters that each have exactly 1 of the same Type, Attribute, Level, ATK or DEF as a Fusion monster, but do not share it with each other as Fusion Material for that Fusion monster ignoring summoning conditions.
Legendary Quest
If you Fusion Summon “Bickuribox”, you can complete your Legendary Quest. If you used 2 monsters with different archetypes, “Bickuribox” becomes part of those archetypes, and the Fusion Materials for "Bickuribox" becomes 1 monster each from any of those archetypes for the rest of the game (ex: 1 “Fluffal” monster + 1 “Shaddoll” monster).
Legendary Relic
(Once per turn): If you control "Bickuribox", you can add 1 "Polymerization" from your Deck or GY to your hand. (Once per turn): If you Fusion Summon a monster other than “Bickuribox”, you can make 1 “Bickuribox” you control gain 200 ATK.
