Hi everyone! I in my second run in Pokemon Uranium and I am in the eight gym. I already have five members in my team. Here my members:

Metalynx/Jason:

Moves: Meteor Smash, Leaf Blade, Giga Drain, Shadow Clawn

Floatzel/Stacy:
Lv: 64
Nature: Sassy

Fallengel:

Navighast:
Lv: 65
Nature: Adamant
Ability: Levitate
Moves: Bone Rush, Shadow Clawn, Thief, Drain Punch

Welp, this is my team until now. I still make the name of my Navighast. My question is what Pokémon I should add? I have some ideas:

Theriamp:
Type: Rock/Eletric

Base Stats:

HP: 75
Attack: 125
Defence: 60
Sp. Attack: 60
Sp. Defence: 80
Speed: 100

Dermafrost:
Type: Rock/Ice

Base Stats:

HP: 95
Attack: 115
Defence: 120
Sp. Attack: 60
Sp. Defence: 70
Speed: 80

Stenowatt:
Type: Eletric

Base Stats:

HP: 75
Attack: 85
Defence: 60
Sp. Attack: 75
Sp. Defence: 80
Speed: 110

Theriamp have some good physical moves and a good speed, both stab and others ones but its have poor defences. Dermafrost is a little more Defence Bulk and with a great variety of moves but lack in Speed and Sp. Defence, and the worse, he have seven weakness: Ground, Rock, Water, Grass, Fighting, Steel and Nuclear. Stenowatt its a good choice too, since he can learn many moves by TM and Move Tutor. What you guys think? What moves I can change in my team? Dont need to be in the competitive, just Story Mode. Say in the comments below.
