Btw I just did the Goldor trial in MC.
What a surprise it took me a few tries but I managed to beat it. The fact that some people are saying everything was an OHKO are lying. You do have a very small wiggle room for error if you're skilled enough to pull back from the brink of death.
I've made a few mistakes but with persistence and patience you can clear the fight once you know how to solve each mechanic....
Just like with EXs and Savage but you don't see everyone complaining about those. I'd say MC ranks much lower than an EX since like I said, you still have a good margin of error and it's simple to memorize the mechanics anyway.
