Here’s the build I’m planning on using for the 2021 format when lightning overdrive comes out with exlord and rekindled rebirth. And yes, surprise, I’m doing laval.
So here’s the list, the deck is a little pricy but it won’t murder you.
2 laval burner
Laval burner can special summon itself from your hand if you have 3 or more laval monsters with different names in your graveyard. It’s a level 5 monster with 1000 defense sadly, because most of the deck likes 200 defense but burner still gets 2 slots in my build for being a free body and is probably the only level 5 or higher laval worth playing in the game at the moment.
3 neo-flamvell lady
Neo-flamvell lady is one of the best cards to run in a laval deck like this one. It gives you a way to stop eldlich and other similar decks with a quick effect, and as an added bonus mills monsters directly from your deck to fill your graveyard with laval monsters! I gave it 3 slots purely for how well it works with laval in general.
3 laval blaster
Laval blaster can dump up to 5 cards off the top of your deck to the grave upon its normal summon provided you already have a laval in your graveyard. This is easily a common situation and laval archer can help you out with summoning it. Though it has 800 defense I still played it at three because of the sheer number of cards it can mill.
3 laval archer
Laval archer is super good. It can self revive for releveling, it provides another normal summon if you use it for a laval monster, and it has out magic 200 defense stat! I honestly love this card in general and I find it to be one of the best tools laval has at the moment, I gave it 3 spots for how helpful it is.
1 laval lakeside lady
This card can destroy a set card but it’s main flaw is that it also ends up clearing your graveyard. You can mill this monster often enough that I only feel to play 1.
3 ash blossom and joyous spring
Ash blossom and joyous spring is one of the best handtraps in the format and not only that but it’s a fire monster! I gave it three slots because if ash is in your deck, it going at 3.
3 laval coatl
Laval coatl is similar to laval burner but it’s a level 2 tuner. Just for being a tuner that can summon itself it got 3 slots
1 laval forest sprite
Laval forest sprite can make your laval gain huge amounts of stats but it really is only being played for being a level 2 200 defense fire tuner.
3 laval volcano handmaiden
Laval handmaiden is an inanely useful card who mills 3 laval monsters! It also has 200 defense so you can mass spawn it with rekindling
3 de-synchro
De-synchro is a spell that takes apart a synchro monster, you can use it to take apart salamander and make dawn dragster or even repeat synchro monster effects.
3 molten construction field
This is an absolute 3 of in laval decks! It can fill out 5 laval monsters combined with handmaiden
1 rekindled rebirth
Grave tunes 200 defense fire monsters but it is a little bricky over one, it’s a nice tool to have regardless though.
3 rekindling
Oh my god, this is toadally staying at 3 in this build, it summons a lot and is a great card in general.
3 searing fire wall
Summons as many tokens as you like. It’s a great tool in this deck.
2 flamvell counter
This can banish a 200 defense fire in your graveyard to stop a spell/trap, I play it because of the sheer amount of 200 defense fires I can mill.
3 infinite impenitence
Free negate
I think the extra deck is mostly self explanatory except for my choice of “Laval Dragon” not “Laval Dragun” whose completely explanatory but dragOn. So why? Simply put its effect is actually super good. It can shuffle 2 laval monsters from your graveyard into your deck to return a card from the field to the hand, but it’s not a hard once per turn which means as long as you have the laval monsters in your graveyard to work with you can keep on doing it, and you mill a ton of laval monsters really quickly with this deck.
None of the combos are exactly linear but you have multiple ways start things and alongside the drawpower this deck provides I’ll admit that in the right hands I feel laval can be a pretty good deck.
Things to consider when piloting this deck:
1: always pick a target if any before summoning neo-flamvell lady and only use her if your opponent has a graveyard, sure she’s a quick effect and everything but you don’t have much protection for her.
2: when using molten construction field try milling handmaiden, handmaiden cane mill two mor handmaidens and then pitch another laval of your choice.
3: if you’re confident about being able to do it and still summon other synchros then summon T.G. hyper librarian when possible.
I didn’t pick out a side deck yet because I don’t know what will happen in the future but if you have any ideas for a side deck then feel free to tell me!
