With the falling of Linkross in OCG, it brings the Infernoble ceiling low and Stromberg provides a house for them. With both Quiet Life and Stromberg, it will be hard for opponent to break our Isolde Halq board. At the same time we also searched both BLS and Immortal Phoenix Gearfried as reinforcement because you are the king and they wont fail you.
The combo is simple, as it is just another Halq/Auroradon stuff. You just need Isolde, add Gearfried/BLS, ss Grappler Angler, make Halq, ss 001, make Auroradon, ss 001, make Arc Light (for early negation), use Auroradon tribute itself and 1 token, ss O-Lion, make Vanguard Roland and use its eff chain O-Lion, make Savage, add BLS at the end phase. You can even put them all at def position cus Stromberg is there to protect.
Stromberg is our best card and main starter, it means Glife and Terraforming are essential. Glife is also a great toolbox as it is a s/t pop and can be summoned from deck by Stromberg. Iron Hans and Knight as our main target, run 2 each as backup cus 3 are too bricky. Renaud is there as it is a plus with Living Fossil. 2 Fire Flint Lady as our best extender and it replaces Grappler Angler if we draw that tuner (Fire Flint Lady ss Grappler from hand and both have same lv1, means u wont need more equip if summoned from Isolde). Quiet Life goes along with Stromberg as floodgate (this deck doesnt run any normal summon anyway). 3 Durendal as advantage cards (you can put another good equips too, like Axe of Fools, etc.). Staples are just there cus f*** meta, man.
Extra deck is just combo pieces and generic links, play double/triple Isolde as follow up play (link climb). For side deck, Gamma is good as it kills S0 while giving us Halq or lv8 synchro.
Pros: Consistent combo, multiple negations, floodgate, staples, and great followup.
Cons: Stromberg banishes 10 (I tried playing 40+ cards but it makes Stromberg chance lower, but at least this deck can OTK).
