Combining Hazy Flame with Fire Formation/Fist cards, it allows you to summon high level monsters much faster, as well as being able to swarm the field with 3 monsters pretty quickly. Together with the "Beatdown!" skill, you can get over most monsters your opponent controls.
Sphynx is definitely the main core of the deck. It helps with special summoning monsters each turn while also being untargetable. Without using Aroma Strategy, you can't get a guaranteed special summon from its effect. But since this deck has a lot of monsters, you'll have a pretty good chance of getting it right by calling a monster. It's often a risk worth taking since being able to special summon a high level monster increases all monsters you control by 300 because of Beatdown.
If you ever get Raven in your hand, you'll always want to summon/set this card first. It's a good card to set if you ever get first turn without revealing your deck, and it will still activate as long as it gets sent to the graveyard. If you get second turn and you want to go aggressive, summon it face-up if you think your opponent has Floodgate Trap Hole, but if you think it's Enemy Controller then set it before using Fire Formation - Tensu to tribute summon into your high level monsters.
It's often better to get Gyokkou from your deck, and then use it right away before you summon anything so your opponent can't chain it to your actions. Getting Tensu can be better if your hands are filled with monsters you can't summon right away. At least this way you can hope to get Raven so you can tribute summon immediately.
You can special summon Goka by destroying another FIRE monster that you have on the field. This works well with Raven and Cerberus because of their effects, allowing you for more follow up plays later. It's better to summon Goka when you only have 1 or 2 monster on the field that you want to destroy, but it's always better to get Peryton out so you can summon 2 monsters from your deck right away. With 2 high level monsters on the field, it's already a +600 attack to each monster from Beatdown. If you summon at least 1 Sphynx, you can then use its effect to maybe summon a third monster for that +900 boost.
It shouldn't work, as it says "banish 1 card your opponent controls". Every card like that requires targetting because how else does DL know which card you want to banish if there are 2 or more cards on your opponent's field?
Not really there are a lot of alternatives the UR ticket prize Dyno something *I'm no good with name* thats an alternative, Earth Armor Ninja is also an alternative, Coyote is also good in conjunction with raven off course.
