Decklist that I used in Master Duel, Tech options can be tweaked according to prefference, in my case I only have one impermanence and one dropplet, and that's why I run the deck like this.
Main strategy is the good ol' Rank 5 into Nova and Infinity, for the omni negate and monster absorbtion, by either luckily drawing Core, Nashe or Hertz + Duplication, or Galaxy Soldier Shenanigans, using Nashe to revive a regular Cyber Dragons...
Having a Cyber Dragon on the field (or ready to be summoned) + Kaiju = Remove anything from the board by summoning Fortress Dragon.
Megafleet does the same but without the Kaiju, you need the opponent's monster to be on the extra zone tho.
Zeus is there a bit just because I have him, never really used it, but could be useful I guess.
Almiraj sends Hertz to the graveyard if you have nothing else.
If you manage to summon Rampage and Sieger you can potentially OTK very easily, Rampage can even win you the game by himself if there's no monsters on the opponent's field and he's at 6300LP or less.
To link climb from Hiita to Accesscode, you'd need to have summoned almiraj at some point and have him on the graveyard, then summon Hiita, so normal summon an Ash Blossom or, link her away with something and then you want your opponent to have another Ash on the GY, (or another fire monster) to revive it when you summon Hiita, then link them away to summon Transcode Talker, and use Transcode's effect to revive Almiraj, and then finally Accesscode, made from a link 3, so 5300ATK.
I haven't really used Eternity, but it is really hard to remove, as long as you have some other fusion machine monster on the GY, and that's easy to do with megafleet and fortress dragons, Eternity will be untargetable and inmune to all effects, so it can only be killed by battle or by dropping a Kaiju on it.
