Magic Trick currently dilutes the shop pool with crap, and my perspective is that a Magic Trick is about "making things disappear"
So here are my ideas for a Rework
Magic Trick: Destroy a random rank in your deck
Illusion: Gain 4 Negative Handed Mans
Negative Consumables don't come up a lot, and this makes both Vouchers do something interesting in comparison to the others.
The cost of a Tarot is usually 3 gold, so the cost of 4 handed men glued together, with the risk of it hitting a rank you want, is very enticing and becomes riskier the longer you do your run.
