Is this something you're willfully bleeding into red or is there some sort of discard theme? Because this is a black effect otherwise (and almost certainly too good with exploit, too, to be at that cost).

What space does this fill that Black Cat doesn't already fill in the exploit archetype?

Forgot about black cat. I was inspired by Noggle Ransacker. How about "each player draws a card, then discard a card at random"? With a bump to uncommon for the time consuming effect?
