Answer 1

I think this is a pretty balance team although there is some things i would have done differently :

• I would have put Scald instead of Water pulse on Mega-Blastoise for a higher power and a 30% chance to burn the target

Blastoise-Mega @ Blastoisinite
Ability: Mega Launcher
EVs: 56 HP / 252 SpA / 200 Spe
Modest Nature
- Scald
- Aura Sphere
- Ice Beam
- Rapid Spin

• Rapid spin on Excadrill is kind of strange since he's holding a Choice Scraf because if you use it, you either have to continue with it (and his poor 20 power) or switch out and let the opponent take a free hit on your switch-in pokemon. Plus you have another Rapid Spinner in your team. I would probably do it more like this :

Excadrill @ Choice Scarf
Ability: Mold Breaker
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Earthquake
- Rock Slide
- Iron Head
- X-Scissor

or get rid of that Choice Scarf and replace it by an Air Ballon to cover temporary his ground weakness:

Excadrill @ Air Ballon
Ability: Mold Breaker
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Earthquake
- Rock Slide
- Iron Head
- Rapid Spin

• It can indeed happens at some point that the opponent uses a sleeping move, but in my opinion, it does not happens often enough for you to have Sleep Talk on your Talonflame (plus, he holds a Choice Band). It could be extremely useful to counter Darkrai but Darkrai's in Ubers and this is an OU team. So i would replace Sleep Talk with Steel Wing for coverage

Talonflame @ Choice Band
Ability: Gale Wings
EVs: 72 HP / 252 Atk / 184 Spe
Adamant Nature
- Brave Bird
- Flare Blitz
- U-turn
- Steel Wing
