Understanding the Megalith Archetype
The Megalith archetype is a series of Ritual Monsters introduced in Yu-Gi-Oh! that specialize in performing Ritual Summons using the effects of monsters instead of traditional Spell Cards. This gives the deck incredible flexibility and resilience. The theme revolves around stone monoliths and ancient structures, symbolizing strength and endurance-traits that also define its playstyle. The main goal is to use cards like Megalith Ophiel, Megalith Hagith, and Megalith Phul to continuously summon Ritual Monsters, generate card advantage, and disrupt opponents during their turn.
