"Will the cards in this structure deck create a new top-tier deck?"
Almost certainly not.
Junks are interesting, but I'm pretty hesitant to think they will be good. Junk Anchor is pretty cool but the cards he can make at the moment are pretty limited.
"Will the cards in this structure deck be used in another top-tier deck?"
Maybe. If Fur Hires were still on top, Gravity Warrior would be a potential way to deal with Wiz, Sage Fur Hire (if you could stop the Dyna, Hero Fur Hire attack), but otherwise this structure deck seems pretty meta-irrelevant.
Gravity Warrior is probably the best generic level 6 synchro at the moment (probably even better than Flamvell Uruquizas). I would recommend picking up a copy of the structure deck for that card alone.
"How do you expect the cards in this structure deck to impact the meta overall?"
I don't think it will impact the meta.
This deck will have as much of an impact as all of the other structure decks besides Destiny Rulers - none!
Gravity Warrior might see some play but that's about it.
