I was playing Pokémon Showdown (Hackmons), and I had a uber stall Shuckle defending against Mega Alakazam. So normally their Hyperspace Hole only dealt 7-10% of my max HP, but on crits, it dealt 35-45% of my health. Why is this? The attacks are hitting on the same conditions (4x SpD), yet deal such different amounts of damage. Don't crits only deal 1.5x damage? The Alakazam's ability was Magic Bounce, so it should not have affected the hit.
