Please don't use those movesets. That will limit your team way too much and leave you vulnerable. When constructing a BF team, you are better off with a special attacker, a physical attacker, and a defensive wall. As you can see, you don't have that. Here is what you want:
Flygon @ Choice Band
EVs: 76 HP / 252 Atk / 164 Spd / 16 SAtk
Jolly Nature (+Spd, -SAtk)
- Earthquake
- Fire Blast
- Quick Attack / Screech
- Rock Slide
This is your starter. QuakeSlide hurts a lot of different types. Fire Blast takes down Steel/Grass/Bugs. Quick Attack is a good finishing move, although Screech can help take down Normal types like Snorlax and Blissey easier.
Sceptile @ Leftovers
EVs: 4 HP / 252 Spd / 252 SAtk
Timid Nature (+Spd, -Atk)
- Leaf Blade
- Leech Seed
- Substitute
- Thunderpunch
The HP recovery you get between Leech Seed and Leftovers makes Substitute practically free. Once the Sub is up, you can deal damage with a STAB Leaf Blade or a Thunderpunch. I prefer a more versatile special attacker, but Sceptile can do, especially against the Swampert you will face at the end of the Battle Tower.
The last slot is up to you. Pokes like Snorlax, Blissey, Suicune, Umbreon, Dusclops, and even Milotic really come in handy since they can take a lot of hits that you wouldn't want you more frail Pokes taking. Here is a Milotic that I have used:
Milotic @ Leftovers
EVs: 212 HP / 252 Def / 12 Spd / 32 SAtk
Bold Nature (+Def, -Atk)
- Hypnosis / Toxic
- Ice Beam
- Recover
- Surf
Hypnosis puts threats to sleep, or you can hit them with Toxic. The others are pretty self-explanatory. It takes a lot to KO Milotic, especially when it gets statused and its Def is upped by 1.5. Leftovers should be used here, but your Sceptile really needs them for it to be effective. You can put something else like Shell Bell for some HP recovery. Just avoid Lum Berry since you want this thing to get statused.
