Once during your turn, after you flip any coins for an attack, you may ignore all effects of those coin flips and begin flipping those coins again. You can't use more than 1 Victory Star Ability each turn.
You can't flip for burns using Victory Star:
>Once during your turn, after you flip any coins for an attack
Burn isn't an attack, so that doesn't apply. Also, you can't flip more than once.
