Which skins affect Csing

skins are not supposed to have any impact on the game other than visuals.

but i have noticed that certain skins make it easier or harder to CS with

some of the ones that make it easier are listed here https://youtu.be/8a8f-x89QPI?t=318 and here https://youtu.be/pc-Wd3jIM7k?list=PLpnvP9blMxw40Dk09FvBjH9CN2rghezpp&t=226

but i was wonder if there are other champs that make it easier or certain skins that make it HARDER. that i should avoiding buying unless i REALLY like it.

because right now after playing jungle and support for seasons 5 and 6, now that im trying to mid again.. i found i suck at CSing,

specifically the skins i am interested in are any of those for my main just wonder even though she jungles.. (mostly use leopard and challenger) my main support who i really need to buy a skin for (use grey chroma, considering new harrowing one my new mid laner, FINALLY got snow day! THANK YOU HARROWING SALE my new secondary mid laner, FINALLY got snow day! THANK YOU HARROWING SALE my old mid laner, (i use snow day) my secondary support/ backup mid laner, mostly use star guardian but use to use steel legion i use my grey steel chroma, becuase i find my "iblitz" skin harder to land a pull with for some reason.

my old top laner and who i may need to get batter at during season 7 when i can choose fill, no skins owned again another jungler, but i don't see a point in trying him again until the assassin changes, use guardian of the sands another jungler, i only ever use eternum
