I legitimately was afraid of getting this guy my first few runs because loosing all discards sounds scary. But +3 hands is actually awesome if you dont have any active synergies with discards going on.
Unused hands contribute money at the end of round. You can burn trash cards on a 'junk hand' which effectively acts like a discard that still gives you points. Having no discards with a positive effect preemptively invalidates the effects of a nasty boss blind.
If you run out of discards but have hands you can still maybe win. If you have all discards but no hands you lost. taps forehead
The only cons I'm thinking is the discard synergyzing cards like... The one that gives you money for each unused discard?? Thats all I can think of. What do you think?
Also, he absolutely wrecks both the Needle and the Water bosses. And has insane synergy with Blueprint/Brainstorm.
The real negative synergies I'd name are jokers like the Castle or the Burned joker, which provide very good scaling for discard value.
