If third hand of round is a single 3, destroy it and add 3 copies of it to your hand
Notes: This Joker is based on a Sierpinski triangle and acts like a much stronger but harder to use version of DNA. It can effectively add 2 copies of a card per round instead of 1. However, it has to be done on the third hand, which checks your ability to play low-scoring hands, hurts your econ if you need to waste hands to stall, and puts you in a potentially risky position to clear the blind with your fourth hand. It also only works on 3s, and while 3s have some fun synergies with Fibonacci (which is especially fitting considering both Jokers have math theming) and Hack, they're overall not too strong. I think it's interesting and balanced, but let me know your thoughts!
