It has come to me that there aren't enough rank specific jokers and face cards get most of the glory. So here are some rank-specific jokers to build around (maybe). Ideas and feedback are appreciated!
[C] Collector's Box - +10 mult if there are no repeat ranks in hand.
[C] Compact Disc - 6 and 9 count as the same rank.
[C] Prism - 3s have a 1 in 4 chance to x2 mult when scored.
[C] Empty House - Create a Spectral card if poker hand contains a full house with no face cards. Self Destructs.
[U] Lucky Slots - Earn $10 if played hand contains 3 7s.
[U] Elemental Joker - Retrigger all played 4s if all 4s in your deck are enhanced cards.
[U] Facepalm - When Small Blind or Big Blind is selected, if there are 5s in hand, destroy them and +1 hand.
[R] To Infinity and Beyond - If played hand contains an 8, add one 8 of a random suit to your hand.
[R] The Universe - x4.2 mult if the rank sum of played hand equals to 42 (A=11, JQK=10)

is the default and people think it's up vote because people use it that way
