So as the title says i am wondering if it is worth it using my ONLY elite tm for the melmetal to use in great league because flash cannon takes too long to get to and also superpower is my only spam, but it debuffs me all the time.
I should also mention that i dont really tryhard in the GBL and only play the great league

Or should i just save it for mega Mewtwo raid and use it for Psystrike or Shadow ball?
