do people here play on cart as well or just showdown? either way which pokemon of the higher tiers are most fun to use? I'm looking forward to raise a new pokemon.

so far I only have:
heatran @choicescarf
Garchomp @life orb
gooda @ assault vest
gardevoir @ choice specs
mega swampert
mega kangaskhan
skarmory @ rocky helmet
darmanitan @ choice scarf
and rotom wash @ chesto berry

most fun to me are skarmory, rotom wash and heatran.

I ave access to all pokemon that can be obtained in AS and X
