Question about telekinesis

Question

Does the telekinesis gaurantee a hit, or does it just negate the evasion stat?

I was planning on teaching my Gengar this moveset, but it wouldn't really be great if all telekinesis did was to negate evasion stat changes.

Answer 1

Telekinesis raises the opponent into the air for 3 turns, causing two effects:
The opponent's Evasion stat is ignored, thus making them easier to hit.
The opponent becomes immune to Ground-type moves.

So, telekinesis does not guarantee a hit, it just makes attacks ignore the evasion stat of the target.
