You can stack things like books, so Gambler's Confidence (50% ^ Profits, with 2 books consumed you get 100% Profit increase), and other items that don't "stack" in the sense of using them at the same time, but rather something like the coin for a free All-In, paired with then using the angel statue to prevent losses at Blackjack tables for early profit.

Hope this helps!
