The goal of this deck is simple, be as destructive and annoying as possible. The addition of ponix has radically improved the deck and now it has some easy ways to setup multiple disruptions. Ponix is a 1-card eternity setup, but having any of the other fire king cards like arvata or immolation can add a layer of disruption. The diabellestar engine is also a 1 card combo, with the advantage of not using a normal summon. This leaves space for an arvata or hanuman summon to help protect you from ash blossom or droll and continue your combo. Book of eclipse pairs well with eternity, as flipping monsters face down would remove any destruction protection they might have from their own effects.
This deck also includes a bit of an unusual tech choice of mannadium torrid, chengying, and baronne. Since torrid is a fire monster and summons a copy of itself upon destruction, it can be destroyed in-hand to trigger sacred garunix or ponix. This will summon garunix and torrid to the field, giving you instant access to baronne and chengying. Baronne can be used when setting up eternity is impossible, or on turn 2 for a free pop and negate. Chengying can be combined with eternity to clear out problematic spells/traps/backrow, or any monsters which would benefit from being in the GY. Since torrid is a fire, it can also be summoned from the GY with circle, and you can easily be able to summon both lv10 synchros.
