Most "Laval" monsters mill and use other "Laval" monsters in the Graveyard. Some, like "Laval Coatl", simply need enough "Lavals" in the Graveyard to work. Others, like "Laval Judgment Lord", banish "Lavals" from the Graveyard for costs. A few, like "Laval Cannon", recycle "Lavals" that have been banished by other effects. The 'dragon' of the archetype, "Lavalval Dragon", returns "Lavals" in the Graveyard to the Deck to bounce the opponent's cards.
All Synchro Monsters require 1 or more non-Tuner FIRE monsters.
Duel Terminal Storyline
The Laval live in a lava zone that's surrounded by Fiery Woodlands. A tribe that's born for battling, all they want to do is fight. For that purpose, they attacked the Gem-Knight repeatedly to start a new conflict. However, the Steelswarms started to take over the surface land. So, the Lavals went to work with the other clans. Forming a temporary union with the Vylon, they obtained new powers to fight back the Steelswarms. Soon, the union finally defeated the invaders, but conflicts haven't lowered yet; the Vylons decided to stop fights between clans by exterminating them completely. Later, the Lavals teamed up with the other clans again in order to stop the Vylon's actions. They fused theirpowers tofight back this order.
After defeating the Vylons, the union disbanded, and the Lavals went working as a new power source for the rituals of the Gishki tribe. Since then, the current fate of Laval tribe is unknown.
Visually, most "Laval" monsters appears to be made out of molten rock or molten lava.
The archetype's name is a corruption of the word "lava", which is similar to how the "Flamvell" archetype was named.
This archetype focuses on completing Graveyard setup, unleash massive swarming speed and overwhelming your opponent with numerous Synchro Monsters. In order to do that, one can utilize "Rekindling" to revive many "Laval" monsters with 200 DEF. Some "Flamvell" monsters can be added to the Deck to increase speed, namely "Flamvell Firedog" and "Flamvell Magician". "Firedog" is essential because it can search for any "Laval" Tuner.
With "Rekindling", this Deck is capable of unleashing the enormous "Shooting Quasar Dragon" on the first turn. Beside "Shooting Quasar Dragon", this Deck also having wide array of Synchro Summoning options, making it quite flexible. "Laval the Greater" and "Laval Stennon" are two Synchro Monsters that are both beaters and prepare for possibly another "Rekindling" combo.
The main plays of this deck consist of sending Lavals to the GY, banishing them via various effects, then summoning them with Laval Cannon while recycling excess Lavals with Pot of Acquisitiveness. Warrior Returning Alive is necessary for retrieving Laval Cannon from the GY easily.
Since Laval strategies are Graveyard-dependent, cards that directly banish cards, like "Macro Cosmos" and "Dimensional Fissure," can seriously disintegrate this Deck. "Necrovalley", "The End of Anubis" and "Forbidden Graveyard" are also dangerous due to it preventing any banishing in your Graveyard, while also disabling the effect of "Rekindling". "Out of the Blue" can expunge "Lavals" from the Graveyard completely, forcing the player to regress their strategy. Anti Special Summon cards such as "Archlord Kristya" and "Vanity's Emptiness" can also force this Deck into a screeching halt.==
Much like other FIRE-based archetypes, this Deck incapable of holding on its own if they cannot get their hands on "Rekindling" quickly. Without it, this Deck usually cannot unleash its full-speed swarming power, and disabling or negating its effect at the right time can be a serious blow for any "Laval" Duelist (albeit "Laval Cannon" can somewhat mitigate this).
Similar to the "Gusto" archetype, this Deck's reliance on Synchro Summoning makes "Discord" an almost-perfect counter against this Deck. A significant count of the non-Synchro "Lavals" have Beatstick-worthy ATK, especially if combined with "Molten Destruction"; "Water Dragon" can wash out offensive strategies.
