I just realised that Champions bundles are mostly just forgotten and stays untouched in your inventory like many standard skins that you buy on your main rifles and maybe knives as well.
You will still stick to your main skinline on your guns and knives, not Champions. 1/3
They don't return in the store like the standard skinlines, the bundles says about the 50% that goes to the teams that are partnered in VCT, but the value of these bundles and anything related to it vanishes once the event ends.
The marketing scheme just worked. Well played. 3/3
