Yeah, I think these are all very good changes.
How did you replenish Wp with just one Curate?
In the five card deck, there was no need to replenish Wp, because I used bargain on the curate before using it. If I ever lacked the initial mp for this to be feasible, I would swap the bargain with the second curate.
The unique quirk of this hero is supposedly to force player to re-evaluate all items, making use of otherwise irrelevant ones just for the triggers.
This creates more interesting choices now, you depend a bit more on finding good triggers, to the point where you might consider rerolling if all useful items lack useful triggers.
