How much do you know about the game? It doesn't seem, to me at least, like you've been following the game very much. If you have though, you'd know that the stone callouts refer to the infinity stones (mind, space, reality, time, power and soul, not in that order in terms of selection on the character screen).
Also, if you don't mind me asking, how much do you know about fighting games in general? It seems to me, given your frustrations with Killer Instinct as well that you might be less aware of how they work. That's fine though, there are likely individuals on here who know them well enough to help you understand the basics.
there are movelists, mentioned in one of my previous posts on this very topic, which should get you started.
