Why are psychic types useless in the Sun and Moon Elite Four?

Question

I have an Alakazam and it doesn't have any effect on Pokemon such as Hariyama. Please help me!

Comments

I am assuming Youngster Joey here persisted longer than a single turn in battle with the fighting type Pokémon in question.

Some people have no patience.

I don't think you're being very specific. What moves are you using that aren't working? Hariyama doesn't have any immunities based on typing or abilities, so what are you using that isn't doing anything.

This should be a comment

My Alakazam could breeze through hala in moon. What is the problem? Are you being taken out quickly? Or can you not attack?

Answer 1

You didn't answer the clarifying questions, so I'll just guess that fake out prevented you from attacking. In case you didn't know, fake out stops working after one turn, so you can attack after that.
