The top 5 highest Yukio card rarities. At number 5 is going to be a tie between the 10,000 secret rare, the Millennium rare, and the Pharaohs rare. At number 4 is the Collector's rare. Now while I'm not personally a huge fan of Collector's rare, these can only be pulled approximately 1 in every 3 boxes which makes them pretty difficult to pull. At number 3 is my personal favorite, the Ultimate rare. Now while these used to be found in main set booster boxes, they can now only be found in OTS packs which are given to you when you compete at your local tournaments. At number 2 is the Ghost Rare. Ghost Rare used to be pulled at a ratio of 1 per case which is absolutely insane and nowadays they can only be found in certain very specific sets. Ghosts from the past as well as Ghosts from the past 2 but otherwise they're really difficult to find. And finally at number 1 is the Starlight Rare. This can only be pulled 1 in every 25 booster boxes. Ghosts 1 in every 2 cases plus a booster box. And now you know.
