Tactical Analysis

I've watched talentless nana and I've seen many mistakes, but I will ask can you do better than the characters on the show here's the side of each you must correct. The antagonist side is how would you kill all talented inside that island more efficiently than nana be realistic and be logical in answers and explain how would you dispose all them but also give suggestions on how to kill the immortal guy.

on the protagonist side how would you as the talented be able to overthrow and destroy Nana but at the same time prove her as a killer and a talentless but also at the same time destroy the organization she works for and expose it.

be realistic on what you say and also logical no powers only technology that is only on our present time no talents or gifts except strategy

This is a little game of strategy and I will also be asking some counterintuitive response on what you answered

Is there anything in this wiki an archetype of a very clever tactical genius, who plays political games with anything and collects authority and influence, who oversmarts everybody to fulfill own purposes and "win the game" like blank from No Game No Life and Palpatine from Star Wars?
