Combos:
The main strat in this deck is to banish card which activates various effects to your advantage with Lavalval Exlord providing some defense and burn damage. Cauldron of the Old Men helps with inflicting that life points while recovering life points if needed. And for fun Dark Sanctuary flips a coin to negate each attack if luck on your side delivers the most satisfying kind of burn damage.
There is plenty of level 7 synchros and lower that are helpful in getting the best level 8 ones out to win. The OCG card Laval Archer help with that and a turner. Laval Cannon uses the same extra summon combo that special summons any Laval monster from your banish zone. Laval Burner can be brought out of the hand with 3 Lavals in your graveyard.
Classic Necroface (Gold Sarcophagus, Pot of Desires all banished back to hand) draw engine as milling (Conductor Field) the deck and then banishing them is your advantage. With there is two Laval Lancelords that are able to get those banish monsters to the hand.
All five trap cards are useful in defense with classic Power of the Guardian, Moon Mirror Shield, and Messenger of Peace for spells.
