Lavalval Salamander →Used Deck

It can also be used as a general-purpose level 7 synchro for the FIRE Deck, and is an excellent card for Laval as a relay point to a level 8 synchro.
You can search for 《Rekindling》and hand triggers with the effect of exchanging cards.
The face-down effect of (2) is not often used, but it is a nice effect to have.

As for the effect of (1), I think it's excellent that you can exchange cards and send him GY at the same time.
For example, if it's a "Laval" Deck, by selecting a "Laval" tuner other than "Laval Coatl" as a card to send to GY, I'm grateful to be able to send GY, increase ATK, and destroy set cards.
By exchanging (2), I think it's a strength that even this card alone can turn one of your opponent's monsters into a face-down Defense Position.
There are restrictions on Synchro Materials, but for example, if it's a "Laval" Deck, you can Synchro Summon it by aligning it with "Laval Lakeside Lady" with the effect of "Laval Archer", so I don't think there's a problem.

The true trump card of the murderous Laval against Steelswarm.
When the S summon is successful, draw 2 cards, send 2 cards containing flames to his GY, and by excluding GY's flames, it has the effect of making the opponent's monsters face-down defense up to the number of Laval on the field.
The summoning ad loss, which is the fate of Laval Synchro, has evolved from a simple hand loss to a hand exchange. Since you draw two cards and discard two cards, the balance is zero, but being able to improve the quality of your hand is a big improvement. The quality of his GY is also important for Laval, so it is also a big point that the number of discarded cards is increasing. A useful effect that can be used for this purpose even in his FIRE Deck other than Laval.
This is not the end, it even has the effect of the book of the moon by excluding GY's flame. It has a killer effect on cards with low defense that makes Gazas in the illustration white, and with his decent ATK, he can break through many cards in battle. It would be even better if the excluded card can be operated with Laval Cannon.
Not limited to Laval, it's a good new addition to the Fire Synchro Deck that takes advantage of hand swaps and exclusions such as Shiranui. Laval is relatively blessed in terms of strengthening this time.

Laval's Synchro Monster corresponds to 《Rekindling》with a monster that cuts your hand when Synchro Summoning is common. However, this is not a demerit effect as it is an optional effect in the form of exchanging cards. However, depending on the situation, you may run out of cards in your hand, so you should consider whether or not to activate it if your hand is low.
The second effect is to use GY's FIRE monster as a cost to turn it into face-down defense without targeting the opponent's monster. Although it doesn't work against Link Monsters, it not only makes it easier to break through monsters with high ATK by flipping them over, but it can also neutralize monsters with strong resistance, so it's a pretty good effect. Destroy the flipped monster with 《Laval Lakeside Lady》or 《Dustflame Blast》. Although GY's resources are reduced, Laval can Special Summon the monsters that were removed with 《Laval Cannon》.
