Rate my team for Pokemon Firered?

I know I need to train more BUT I'M LAZY TO. I just need some opinions about the moves and the levels they should be in. PS: don't make me level up all my pokemon to level 100.

Blastoise Lvl 78 (Trained it from Lvl 5)

Hydro Cannon

Hydro Pump

Surf

Dig

Mewtwo Lvl 73 (Trained it from Lvl 70)

Frustration (it sort of hates me)

Recover

Solarbeam

Psychic

Raichu Lvl 73 (Trained it from Lvl 3)

Thunder

Focus Punch

Mega Kick

Thunderbolt

Pidgeot Lvl 62 (Trained it from Lvl 3)

Wing Attack

Aerial Ace

Fly Return (It LOVES me)

Dewgong Lvl 48 (Trained it from Lvl 25) (I know it's weak so give A LOT of opinions on this one)

Take Down

Icy Wind

Aurora Beam

Surf

Articuno Lvl 51 (Trained it from Lvl 50) (Yes, yes, I'm gonna train this one sooner or later)

Rock Smash

Agility

Mind Reader

Ice Beam (I usually use this move)

I used this team to defeat the Pokemon League once when they were all about the level 50. Now, is this team okay for the second time?

My suggest:

Make Blastoise learn Ice Beam (discard Hydro Pump) or Earthquake,

Make Mewtwo learn Shadow Ball, or Thunder Bolt, Ice Beam,
