Laval

The graveyard is both the fuel and the foundation for Laval decks. Virtually every meaningful effect the archetype possesses either requires Laval monsters to already be in the graveyard or actively sends more there. Molten Conduction Field dumps two Laval monsters from the deck at once, Laval Volcano Handmaiden chains further sends when she herself hits the graveyard, and Laval Blaster mills up to five cards on Normal Summon. Once three or more Laval monsters with different names are resting there, Laval Burner and Laval Coatl Special Summon themselves from the hand, opening the path to Synchro plays without spending Normal Summons on Tribute fodder.

The Synchro suite is where the deck converts that graveyard depth into pressure. Lavalval Dragun recycles resources by adding a Laval monster from the deck while sending another to the graveyard, keeping the engine turning. Lavalval Salamander draws two cards and then filters the hand. Lavalval Exlord threatens to destroy any monster whose effect activates on the field or in hand, punishing the opponent for playing through it. Laval the Greater and Laval Stennon both protect themselves by banishing Laval monsters from the graveyard rather than being destroyed, meaning the graveyard doubles as a defensive resource once established.

The banish pile is a secondary economy rather than dead weight. Laval Cannon retrieves a banished Laval on Normal or Flip Summon, Laval Lakeside Lady destroys a Set card by banishing herself and a graveyard companion, and Dustflame Blast converts a full graveyard into mass removal. This means decks that heavily disrupt early graveyard access, such as those using Dimensional Fissure or Macro Cosmos, can starve the archetype of the raw material everything else depends upon.
