Is learning Trick or Treat worth it?

Question

My Gourgeist knows it and I was wondering if I switch it with something else or not.

Competitive or In-Game?

In-game, but I guess you can also answer in regards to competitive if you want.

---

Competitive: Not really worth it
In-Game: Maybe, since you can make your opponent be a Ghost Type, then you can hit your opponent with a STAB Ghost type move for super effective damage,

I think I have a good competitive approach to it, but I'm not gonna bother. xD
But yeah, in-game it could be great since 'cos then Gourgeist can use a STAB Ghost move, then for Normal types you could just use a Fighting-type move. :D

Answer 1

I have found Trick-or-Treat to be very useful, due to making Pokemon weak to your Phantom Force who would otherwise have immunities. It also can shut down Dark types due to the added weakness and gives Gourgest great coverage.

Competitvely, I wouldn't recommend it, due to Pokemon already dropping you to low HP the turn you use the move.

Is this the same with Forest's Curse?

---

Yeah, basically.

This makes Scizor w/ Forest Curse 6x Weak to Fire! :O

---

6 or 8 (2X2X2=8)?

I wouldn't say forests curse is as useful in a single battle, but Trick or Treat I find very useful.

Answer 2

I have found it a very useful move in competition myself but my it fits the role I have my Gourgiest fill of a stall/set up unit for other Pokemons move sets. Substitute followed up by trick or treat, then sitting behind the Substitute using leech seed and foul play with the giest works very well for me though mine is built as a HP/defense tank to support rest of line up.

It makes everything weak to my dark types with their STAB dark moves. I don;t run a STAB move on my Giest as it has such low Attack and Special attack foul play hits harder still being based on targets attack.
