Yes, you can use any stationary legend/wild pokemon to calibrate ^^
Oh, I see. I didn't know that :/
Ok, I can help. Do you have a seed that you're ready to hit? Because calibration this generation is attempting to hit a seed. Also, you need a way to verify IVs for this :/ It would be really helpful if you had an AR, but you can either calibrate on a really high leveled wild pokemon/legendary, or use Rare Candies to level a pokemon to a high level, and then use an IV calculator.
So, tell me when you have a seed you want to try to hit :]
