Classic PK Fire strategy: build your board to Arc Rebellion XYZ Dragon via Cherubini and Rusty Bardiche. Spiced up by the small Isolde engine with Renaud and Fire Flint Lady, the equip spells are necessary for Isolde's effect but kinda usefull on it's own (D.D.R. is a free Leviair basically). No RotA it's a necessary decrement, but it's not as a big of a deal as having 46 cards that feel a lot heavier, if I'm not satisfied by the Isolde engine I'll switch back to RotA.
DPE it's always usefull, with the banning of Anaconda and Fusion Destiny Semi-limited isn't a free turn 1 play, and there could be games that you can OTK even before having to place the HERO (please note: also GET OTKed, this deck isn't as powerful as some formats ago and surely isn't as powerful as Adventurer Variant).
In hand you'd like one of those cards: "Tour Guide of the Undeworld", "The Phantom Knights of the Torn Scales" or a Danger!?, usefull extenders a Foolish Burials, Emergency Teleport and the chain locking Kagemucha Warrior are perfect for a faster OTK. In 10 starting hands that i played only one bricked (before I added Almiraj), so the deck is still pretty consistent, and looses hard to Nibiru or some form of interruption.
Finally, the deck is still lots of fun and I think still a worthy opponent as a T2/rogue deck in T1 formats, side deck varies based on the event I've put cards that I think will be usefull most of the times (if Anti-Fragrance gets banned I would put some form of interruption for Depia and Sky Striker, probably a Veiler to stop their strategy on a monster effect level). I hope to get some more advice on the build, as the last time.
