My thought why I chose those Pokemons:
Sceptile is my lead, special attacker and force the opponent to switch their Pokemons with Leech Seed. Skarmory takes advantage of that by planting Spikes, and in addition functions as the physical wall of the team. A defensive Starmie rounds up the resistances, and serves as a special attacker and as the spinner of the team.
Those three are the core of the team.
Next are Swampert and/or Metagross. They add more resistances to the team and serves as physical attackers. Both could properly also serve as leads.
Which one should I choose? Should I change their builds, e.g. into a Choice Band Metagross? Or maybe a totally different Pokemon would fit better into the core team?
Next is the special wall. I lean towards Dusclops, as it can somewhat serve as a physical wall as well, hampers physical attackers with Will-O-Wisp, damages special attackers with Toxic and prevent enemy spinners from doing their job. It can also absorb a Focus Punch from Focus Band Heracross. However, Gardevoir could serve as a cleric and hamper physical attackers as well, however cannot withstand physical attacks.
Would it make more sense to run Toxic on my Skarmory when I replace Dusciops with Gardevoir?
Now I wanted a second physical attacker, and as my team until now has two to three Pokemon with weakness to fire I wanted a fire Pokemon, or at least one that is resistant to fire. Blaziken has two STABs, great coverage, but it is somewhat fragile and slow. Arcanine adds a +1 priority and a dark attack, both of which my team is missing. Another option would be Flygon, as without Swampert I have no STAB Earthquake.
What Pokemons should I choose? Can one build a solid team out of these? Is there any huge weakness my team has that needs to be fixed?
