i need some suggestion for my team

sorry if this is in the wrong area.

But i cant use my mew and latias for alot of things so i want to replace them.
So please tell me two pokemon i should add to my team with the nature and move set.

My team so far is


Umbreon Hasty
Dark Pulse
Iron Tail
toxic
moon light


Gengar Jolly
Dark Pulse
Thunder Bolt
Shadow Ball
Focus Blast


Gallade Adament
Close Combat
Leaf Blade
Psycho Cut
Night Slash


Milotic Modest
Ice Beam
Surf
Rest
Sleep Talk

I dont know about ev training when i raised them so i dont know that much.

Make Gengar timid. Instead of moonlight give Umbreon wish, I also wouldn't recommend iron tail and darkpulse, maybe pursuit although I don't recommend an Umbreon. Milotic, replace rest with recover and sleep talk with hypnosis
