Watching pro matches, you often see a wide variety of different skins used by the pros. Despite that, a four person spray down is worth the same even if you used an unskinned M4A4 instead of Howl. The only effect skins have is aesthetics. With that in mind, I was a little bit disappointed when I watched n0thing’s matches with the specific purpose to see which skin he uses because he barely showed off any, resulting in a short article. I can understand the decision, though.
Keeping in mind that n0thing is American, I would almost suspect that he’s trying to show off his country’s colors with his skin choices. That or he’s trying to represent his team, C9. In either case, he uses StatTrak Glock-18 | Water Elemental, P250 | Undertow, P2000 | Fire Elemental, StatTrak Tec-9 | Blue Titanium, and, for some reason, AWP | Asiimov, even though some kind of blue, red, or white AWP skin could certainly be found. To be fair, Asiimovs ARE white with orange (which is somewhat close to red) highlights.
I do not believe that n0thing’s clear lack of skin presence while in game is due to him not having any because looking through his inventory, he has 51 knife skins, yet uses the default, 99 rifle skins, yet uses default rifles, you get the point.
