As it says you can't use more than one Victory Star ability per turn. Plus, the burn flip is in between turns if I remember right (if not, sorry, burns were after my time). If it is in between turns then you wouldn't even be able to use Victory Star. As it says, it only works on your turn and only for attacks.
I do realize that there is an error on TCGO that makes it (Victory Star) work differently. However, for the hard-copy TCG the rules I listed above are in effect.
