I have a ton but not enough to deduce some sort of variations chart. From what I’ve seen you can get any pokemon on any color of marble and I’ve also seen the same pokemon on different color bags before. I try to buy the marbles and bags any time they pop up for relatively cheap. Maybe one day I’ll have a large enough of a collection to make some sort of guide to them.
Here’s what I have. I also have a few more bags not pictured. At the top is the marble launcher that was used when “battling” with the marbles. You used the mat as a stage and tried knocking everyone else’s marbles off. For being produced in 1999 the technology is actually pretty cool. You can load several marbles into it, shoot one and then press a button where a motor spins the loader and drops another in ready to be shot. It also has a built in light! There’s also a huge pokeball shaped storage case that was made. I’ve been on the hunt for one of those for a while but anytime they pop up they are too expensive for my liking.
