if all 22 are on the workshop, valve should then make a seperate case for them, considering they are all high tier looks, pinks and reds (maybe purples) they should make it a more rare/expensive case which only drops these skins, but they are all pinks and reds.
So maybe lower drop rate or higher key price

BONUS for the case, instead of knife skin or gloves, ZEUS SKINS (+stattrack ofcourse)? :O
