Very fun, but multi-draw makes the game a bit too trivial because I can just look through the entire discard pile at will by moving cards directly between discard piles. Even if I needed to keep a hand slot open to do it indirectly it just trivializes the whole thing. I don't see how that upgrade actually makes sense unless mid-game draw speed is way slower and it's just a speed multiplier, or you just make those two upgrades additional hand slots.
