Honestly not a bad all round deck, I would definitely not use it for tournaments and such but otherwise I find it much more fun than the meta decks out right now, feels a lot like a deck that would be used in the anime by a side character.
There is no 1 way to play this deck, that's what I like so much you can make so many different moves and strats and Fire king is probably my favourite archetype so download it and have a blast.
I would say the most fun combo would be dumping a bunch of 200 def and then rekindling 5 monsters and xyz-summoning Crooked cook and using his effect to clear your field which can activate the fire king effects and also gives him high attack.
