This is just a matchup chart thing I made. You can use it to compare which characters have an advantage over others, and which have a disadvantage over others. Here is the game https://scratch.mit.edu/projects/318927435
what most of the matchup chart is about is if chrarth can be above you to do downair upair and also if they can be edge guarded, the reason the smaller characters are better are that they can avoid combos and because they are lighter also avoid them that way, the good matchups are because they have bad recoveries, and metron also wants to be above you and has a mediocre recovery so its even.
