I Have the Answer to Mega Malamar

also I use a 4x super effective bigger blade from ceruledge

This made me laugh but who, what, and where does Hoopa use Hyperspace Hole

My Ceruledge twists, its left blade sadly getting hit, but it avoids most of it, falling into a hole next to it and popping out of one behind me. I immediately use a Full Restore.

Simultaneously with the diving into the hole part my Gardevoir used Moonblast on Zorua!

I use Agile Style Mystical Fire to h1t first

I'm not sure if it does work as priority.

Legends Arceus doesn't have abilities, so we couldn't find out.

However, I know it can be combined with priority moves, so I don't think it is one.

Agile Style let's the Pokémon move faster but decreases the base damage by 10 or 20. There is also a Strong Style, which gives your Pokémon 10-20 more damage but it has to wait longer for its next attack.

Anyways, back to what I was saying, there is a strategy that you use Agile Style Bullet Punch, which naturally let's it move quicker, then use normal Bullet Punch, then another Bullet Punch because the turn system was different in Legends Arceus.

Based on that, though, I don't think it makes it a priority move because then it wouldn't make sense on why there still is priority moves.

I could be wrong, though.
