Volcanics pieces are the usual Rocket/Blaze/Shell as the main package.
Since we are going to run other Volcanics for theme, Doomfire and Queen are available as the next pieces that have a decent function.
Lava Golem fits as an inbetween with Doomfire's Stats and Queen kaiju.
With 6 Lv8 monsters now, 3 Trade-ins is possible to just cycle out between trying to Summon either Doomfire Beatdown or stalling with Lava Golem.
Because we are running both Queen and Lava Golem, Remove Brainwashing becomes available, you can tribute up to even 4 of your opponent's monsters for Double Lava Golem. Then flip Remove Brainwashing in the attempt to regain control after your Standby Phase in your Main Phase 1
Since we are running Kaijus, we can even choose general Floodgate options to force a tribute or force the opponent to set monster(s)
In addtion with the fact that we will also be having to deal with our own Kaijus, we can run Threatening Roars and our single Magic Cylinder.
with 3 Removing Brainwashings and possibly 2 to 4 more other continuous traps, Magic Planter becomes available for turning off "wasted" face-ups
Running almost 7 to 9 Continuous, Uria can be yet another Boss Monster that also has all the same Attributes/Type/Atk 0 to be used for Blaze Accelerator or as another flex option, since it can come down and remove 1 Set Spell/Trap per turn to carefully kill the opponent's resources.
Monster Gate with Rocket or Shell to double the summon effect of an excavated Rocket, chances are optimal play is Normal Summon Rocket > Monster Gate > Rocket. since the only other possible target is Rocket or Shell, you can simply pay LP to add the other Shells until you have none ensuring 100% Rocket > Rocket play for Blaze into Tri-Blaze when Doomfire is in Hand.
Card Destruction, MST, CotH are all other powerful arsenal tools, with Card Destruction being one of the few ways to remove handtraps (when possible), MST removing the 1 Face-up or Set Spell/Trap that might be problematic, and CoTH for any and all successfully Summoned Lava Golem or Doomfire.
Side Decking can be used: between Gozen Match or Rivalry of Warlords, adding more Stalling card with Waboku and Compulsory Evacuation Device, and lastly, Scattershot and Royal Firestorm Guards for added Pyro recycling and more Draw 2s
