how do cases/crates work?
a case from say 2024 smissmas no longer drops now since the season is over, does that mean no more of them can come into existence? they aren't added to the official store? if not, then does that mean that all the hats/skins/etc in old cases become limited and can only be obtained through trading? am I unable to purchase several old cases/crates to get some old hats and not have to worry about prices being high and essentially burning through a finite supply of both cases and keys? seems sucky if so, what if I wanted the "gift bringer" cosmetic from the tough break case (which no longer is created), is there a finite amount of gift bringers in tf2?
