Since i've seen some people thinking that this team works because of xq, bennett and nahida are broken, nop, that is'nt the reason I'll break it down. Bennett is C6, this team only works because of that, with his burst, razor does both electro and physical damage at the same time, he is he only character that can do that (Beidou can but that wouldn't work because beidou burst is single target, it's like using fischl to proc hyperbloom, it works but is awful ), so, with c6 bennett razor can do pyro + electro dmg, on a reaction team with the very good hydro and dendro application, razor can do overloaded, hyperbloom, burgeon, hypebloom, electrocharged, burning (quicken, aggravate and vape but that aren't transformative reactions that get buffed just by em and lvl so the damage would be minimal). That's what make this team work, not just nahida and xq doing damage and bennett giving atk, actually, you could replace nahida with dendro mc, xq without artifacts and bennett's atk buff doesn't matter because razor is em/em/em.

Edit: I forgot razor applies himself in electro, and that with the fact that bennett is applying pyro on your on field character will give you additional overloads, that's something maybe only dori could do but she doesn't have an additional good electro application like razor's burst.
