This archetype based on a character on YouTube Show “Revelation of the Orichalcos” named “Chimaira”, one of Valtor’s general. His deck’s themed after the name of each “7 Deadly Sins”.
This archetype focusing on creating Dummy Monsters from Spells or Traps, their effect revolves on discarding either your hand or your opponents. They can “shapeshift” into monster when discarded into a gargantuan monsters with huge ATK or fearsome effects. During chimaira’s debut, he rellies on “Pentacle Gear” for discard engine to perform shapeshifting, but with their new support, they more than capable to completely swarm your opponent with giants or monsters with crippling effects. They possess the power to summon their boss “Zero God” DIVINE monster to deal the finishing blow if your opponent can somehow survive the onslaught.
They however, very suspectible against tactics that involves special summoning a monster(s) that is not “Pentacle” monsters into your field since they will “self terminate” if you control monsters that is not their own kind.
