Fusion Devourer (archetype)

"Fusion Devourer" is an archetype of DARK Fiend monsters, (except for "Fusion Devourer - Chaos Archfiend Golem" whose Attribute is LIGHT) which the most infamous monster being "" itself. Despite their names, none of monsters from this archetype belong to the Fusion archetype, except for 1 Spell Card that does support this archetype.

Playstyle
Most of the archetype focused against decks that purely relied on Fusion Monsters. Ironically, many Fusion Monsters from this archetype are unaffected by the effects of all "Fusion Devourer" monsters. They also focused on swarming the field to be used as fodder for Xyz Summoning Rank 4 Xyz Monster.

They work well with DARK Fiend monster, as most of the "Fusion Devourer" Fusion Monsters required at lease DARK Fiend monsters as Fusion Material (including "Fusion Devourer" monsters themselves).

Because all members of this archetype are Fiend monsters, cards such as "" can be useful in this deck, as is "Raviel, Lord of Phantasms" from the paragraph above.

Weakness
Because they are focused against decks that purely relied on Fusion Monsters, they don't do well against decks that don't used Fusion Monsters at all, like a "Blackwing" deck for example.

"All members of the non-Extra Deck monsters has low ATK to up to 2000 ATK range, which caused them to be destroyed by powerful non-Fusion Monsters, so it's recommended that you use cards such as "" to make them strong enough to take those monsters out.

Because of the above weakness, "Fusion Devourer" Fusion Monsters are just beatstick monsters, though "Fusion Devourer - Chaos Archfiend Golem" would still a formidable monster because of its effects.

Because all of them are Fiend monster, cards such as "" can cause problems for this archetype.
