Volcanic Ashen

The goal of the deck is to use the volcanics to link climb into Promethean Princess, Bestower of Flames & Amphibious Swarmship Amblowhale while special summoning Volcanic Emperor to setup a negate with Volcanic Inferno. Then using the ashen cards to setup a board wipe to simplify the game state and flood the grave with pyro monsters to use to summon Emperor from grave. Emperor comes back every turn (ideally to an empty field) and burning the opp.

This deck can probably be refined to create space for hand traps. Going second tools are baked in (ex: Radian, the Multidimensional Kaiju turns on King of the Ashened City if we don't have Veidos the Eruption Dragon of Extinction ) & volcanics targeted removal.

An ideal hand is Volcanic Trooper & Awakening of Veidos + discard:

Step 1 - Link climb with volcanics.
Normal Volcanic Trooper & use effect to get Volcanic Blaze Accelerator.
Activate Trooper by discarding (not Awakening of Veidos or Volcanic Blaze Accelerator) to summon token.
Activate Volcanic Blaze Accelerator to destroy the token by sending Volcanic Rimfire to the GY.
Activate Volcanic Rimfire to send Volcanic Emperor to the GY.
Special Volcanic Emperor with it's own effect by banishing the Blaze Accelerator (sent to GY to activate Volcanic Blaze Accelerator).
Activate Volcanic Emperor to set Volcanic Inferno from the deck.
Link summon Flametongue the Blazing Magical Blade with Emperor & Trooper.
Use Flametongue the Blazing Magical Blade to add the banished Volcanic Rimfire to hand.
Activate Volcanic Blaze Accelerator to special summon the Volcanic Rimfire.
Link summon Promethean Princess, Bestower of Flames and use it's effect to revive a FIRE from grave.
Link summon Amphibious Swarmship Amblowhale.

Step 2 - Setup Ashen's board wipe.
Now activate Awakening of Veidos (which will force a Pyro lock so must be done after the Link climb).
Place Obsidim, the Ashened City in the opponent's field to allow a search of Veidos the Eruption Dragon of Extinction.

Activate Veidos to destroy Obsidim & set Ashened for Eternity (special summoning Veidos to the opponent's field; Don't activate Promethean Princess, Bestower of Flames despite the condition being met.).
Activate Obsidim, the Ashened City to special summon King of the Ashened City.
Use King of the Ashened City 's effect to special summon Hero of the Ashened City from deck (because Veidos is on the opponent's field).
Use Hero of the Ashened City to destroy Veidos the Eruption Dragon of Extinction & activate Obsidim, the Ashened City from deck, but don't activate Veidos' effect when destroyed.

During the End Phase Obsidim draws a card. Ashened for Eternity can add back Veidos the Eruption Dragon of Extinction at the first opportunity to setup a board wipe (even if Hero of the Ashened City is removed from play Promethean Princess, Bestower of Flames can destroy Veidos).
