The one block that I have always wanted is a refill crate.
E.g host puts things in crate, player takes things out crate (that player can't take that thing out crate again) a different player comes along and takes the same thing out the crate as the last person but after can't retrieve things from that crate again but players that havnt been in the crate yet can
Or a crate that has a timer and refills after a certain amount of time
