-# theme wise this is mult castle
-# HOWEVER big note, the selection process for the rank is inversely proportional to the number of each rank you have in your deck.
-# ex: 10 cards in deck, 7 aces, 2 kings, and 1 queen. A random float from 0 to (1 + 1/2 + 1/7) is generated. If the float is from 0 to 1, queens are the chosen rank, 1 to 1.5 kings are the chosen rank, 1.5 to to 1.642 aces are chosen.
-# tldr: the rank selected is more likely to be a rank you have less of in your deck
-# may change the actual formula but that's the jist
