From Bulbapedia, the community-driven Pokémon encyclopedia.

Trick-or-Treat (Japanese: ハロウィン Halloween) is a non-damaging Ghost-type move introduced in Generation VI. It is the signature move of Pumpkaboo and Gourgeist.

Effect

Trick-or-Treat adds the Ghost type to the target, in addition to the Pokémon's original type(s). If it is used against a dual-type Pokémon, that Pokémon will have three types at once. If the target already has an additional type added to it by Forest's Curse, that type is replaced with the Ghost type. Trick-or-Treat will fail if the target Pokémon is already Ghost type. This additional type can be copied by Reflect Type.

If powered up by a Ghostium Z into Z-Trick-or-Treat, the user's Attack, Defense, Special Attack, Special Defense, and Speed are raised by one stage each.
