Forum:Am i doing it right?

Hi, i want to know if this is right or if im cheating.

I run a Shooting Star Dragon in my deck but i don't have any Tuner Synchro monsters like Formula Synchron, so I normally use my Gaia Knight, the Force of Earth in a chain with Level Retuner, Level Tuning and Natural Tune to summon it. I just want to know, am I cheating or is it completely legal? Haos_Serpenoid_500
