Should i have Gengar or Muk in my team.
The rest of my team is:
Aerodactyle
Snorlax
Varoreon
Magmar
Blissey(mabey)
So which of the two is better for my team

Wat r their movesets?

Snorlax
Rest
Brickbreak/earthquake
Bellydrum
???


Vaporeon
Icebeam
Surf
Haze
Acidarmour

Magmar
Flamthrower
Thunpunch
Confuseray
Smog/irontail

Blissey
Aromathrapy
Toxic
Softboiled
Metronome

Aerodactyle
Acientpower
Wingattack
Irontail
Doubleteam

Snorlax-Physical attacker
Shadowball or return as last move. EQ is better than brick break.

Vaporeon-?
Sponge or hazer? If sponge, drop haze, if hazer, drop acid armour.
Better as a sponge though. Drop haze for toxic. Rest is a good move too.
Baton passing the Def gain to snorlax would also be a very powerful move.
If you want a sponge that can haze, use skarmory or weezing.

Magmar-Special attacker
Try this moveset though.
Flamethrower, HP Grass, Counter, Thunderpunch

Blissey-special sponge
Replace metronome with counter. You may also want to replace aromatherapy with ice beam, depending on who u fight with.

Aerodactyl-Physical attacker
Use the moveset i provided. Aerodactyl cannot survive long enough to double team, plus choice band on it is deadly. Rockslide is more powerful than ancient power. Earthquake is always a deadly move.

Both Muk and gengar would do well in your team, but i prefer gengar.
A common moveset for gengar is: shadowball, substitute, focus punch, ice punch.

the thing about vaporeon is that i would have to start overwoth it again it didn't learn baton pass i onlu realised that after i stated and its around level 40 if there ia any other way to get baton pass please tell.
How can i change what type hidden power is.

As far as i am aware, the type and power is not changable but determines by each pokémon.

its all dependant on ivs i read up
but thanks any way and im not gonna restart vapoureon i might get lanturn instead
