Forum:Gantala and pot of duality

If I have Gantala on the field and I play Pot of Duality, will Gantala's effect activate in the end phase or will Pot of Duality's secondary effect stop this from happening.

I'm jsut having a little difficulty because im not sure if the end phase counts as part of my turn or if its the space in between mine and my opponents.

Clarification on this matter would be greatly appreciated.
