If that's not enough, Gengar is capable of bringing 2 mons down on its own by killing something with its offensive moves and then (when you're in Sash range) finishing the second mon with Destiny Bond (Psychic terrain protects you from priority moves). Mega Mence is self explainory.
Battle Tree is really not that hard when you realize the best thing you can do is just attack, attack and attack.
