It's been tested and proved that creatine is only good for weight lifting and other sports where you lift heavy stuff and not good for endurance exercises. Creatine phosphate is used in the process ADP -> ATP where it donates 1 phosphate so the ADP turns into ATP (energy), therefore making your muscles ready faster... I don't see how creatine would fuck up your cutting as it only makes you retend more water(essentially retending more water makes you stronger) and of course makes you recuperate faster...
