The question is simple. Imagine you died today and got resurrected to choose your new life. Think of it as a shitty isekai anime.
Where would you want to live,why?
Who would you want to live with,why?
Whose power or shop item would you like to have,why?
Noxus,because all other nations are for betas.
Ahri,for reasons. (Imagine if Ahri dressed like a Noxian!)
Yorick because summoning an entire army of corpses would be very useful and versatile.
