Suggestions for random selections.

[Seravorn]

I would like to be able to select for random options based on what cards do rather than the set they are from.
For example, to select a random card that has +1 buy, or +2 actions, or is an attack, or is a night, etc.
Similarly, i wish i could select cards to be random based on cost. Id like to generate a table that has 1x 2 cost, 2 each of 3, 4, 5, and 6 cost, and 1 other. But you cant do either of these things.

It would also be nice if you could save set ups so i can test a build and then share that with a friend easily later.
