The deck is full of odd cards, so the holographic Odd Todd at the start can be useful as a boost throughout the run. You can win without much trouble with a pair build, although the Space Joker that´s found early and the Astronomer you can find before getting Supernova may allow you to experiment with other hands. There was also an invisible joker by ante 4 i think? (I did not use it tho). You can find Chicot by ante 3?, I recommend it to avoid The Ox later on.
