Is there a reason Umbreon learns Synchronoise?

Synchronoise is a move that has 120 Base Power. At first, it looks like a better version of Psychic. But it has a twist.It can only hit Pokemon with the same type as the user.Meaning that if a Umbreon uses it, this PSYCHIC move willonly hit Dark type Pokemon.but Dark is not affected by Dark Type Pokemon. So what’s the point of having it on Umbreon?

The point ofUmbreonbeing able to learnSynchronoiseis because its pre-evolution,Eevee, can learn it as an egg move. If Eevee can learn it through breeding, so can its evolutions.

Unfortunately, you are right that the move cannot hit Dark-types, like Umbreon.

As you see, Synchronoise is learnt by breeding, and that Eevee learns it by that method.

As Eevee evolves into Umbreon, Umbreon has that move as well, despite being as useful as Splash in the context.

This is seen in many moves. Any moves Eevee learns, the Eeveelutions invariably learn. This is how they’re coded, and makes sense in general. Sometimes, due to the generalized methods, you get useless combinations like the one you mentioned. There’s no point for that, just that deletion of moves from a moveset upon evolution is somewhat absurd, and is rarely if ever, seen. If a Pokemon knows just one move, and evolves, but the evolution doesn’t learn that, then there’s going to be trouble. Imagine your Eevee knowing Tackle, and just before it evolves into Umbreon, you delete every move apart from Tackle, which, say, Umbreon can’t learn (for example). Will you get an Umbreon without moves? Same principle here.
