Use "Molten Conduction Field" to send "Laval" monsters from your Deck to your Graveyard. Then, banish all of your "Laval" monsters to activate "Dustflame Blast" and destroy cards on the field!

Then, Normal Summon "Laval Cannon" to Special Summon one of the "Laval" monsters you just banished!

If the Laval monster you Special Summoned is a Level 1 Tuner Monster, you can Synchro Summon "Lavalval Dragon" or "Laval Dual Slasher." If the monster is a Level 2 Tuner, you can Synchro Summon "Lavalval Dragun"!
