This weakness basically reads...
-Discard an Asset you control. For one round you get -1 willpower. -On the next round, discard occult scraps and play an asset for -1 resource cost.
It's a unique weakness that can actually be helpful in some circumstances. If you have a fully tapped spell, this is a way to clear it. Coupled with showmanship, you can possibly have a super turn on your next turn.
