From my observations in the past two SG events as well as this one, you definitely get put on the list if you level up as long as you have at least one gem; otherwise, you just have a really high chance of being put onto the battle list once you get your 5th gem. (I think you can be put onto it when you find your 1st, 2nd, 3rd, or 4th gems outside of leveling up, but the chances for that are pretty small.)
