Pyro Sweets/Earth Pyro is a deck that mainly focuses on a basic beatdown strategy by swarming the field with the deck's 3 main beaters: Dogulce Jomont Blanc, Dogulce Langue de Chakok and Dokidoki Hexenhaus; and boosting their atk with their key spell Dried Fruit De-kako-ration. This allows to essentially beat over any monster in the game along with the rest of Pyro support cards and other tech cards to consider.
Dokidoki Hexenhaus is the ace monster of the deck, and allows for easy swarming of Pyro beaters by summoning any normal pyro from the graveyard on the turn is normal summoned. So is always ideal to have Blanc on the gy as soon as possible to make use if its effect.
Dogulce Langue de Chakoki helps setting up the GY for the necessary pyro monsters to use with Hexenhaus and De-kako-ration, on top of also retrieving any pyro boss monster from GY in cse they are needed like Spice or another Hexenhaus to keep the combo going.
Dried Fruit De-kako-ration, the key spell that gives the deck its main strength by shuffling back pyro monsters back to deck and recovering a bit of LP to keep your advantage over the opponent and maintain your resources.

Fiery Blaze
