Long story short, I was looking at the mechanics of the move Nature Power and found something cool. As of gen 6, the Terrain moves (Grassy, Misty, and Electric) will change what Nature Power turns into.

This means that any Pokémon with access to Nature Power can also fire off Energy Ball, Moonblast, or Thunderbolt with the right terrain in place, not to mention the added benefits of the terrain boosts.

Any ideas for sets involving this?
