In case you are not aware, when you terastalize, moves of your tera type that are not priority or multi-hit that are under 60 BP become 60 BP.
What I want to know is this: does Technician activate first or does Tera activate first? Here's an example. Say my Scizor terastalizes into the Steel type, and uses Metal Claw, a 50 BP move. If Technician activates first, it would make it a 75 BP move, and Tera Steel wouldn't do anything, because it's no longer under 60 BP. However, if Tera activates first, it would make it a 60 BP move, and Technician would boost it to 90 BP. Would Metal Claw be a 75 or 90 BP move?
Thanks for your help!
