I never thought RNGesus would let me see the day, I finally got a 50 win streak (in doubles non the less! The format I suck at!) Freaking love Trick Room.
Oranguru @ Mental Herb (The ai eventually gets smart and stops using Taunt so mental Herb's use sorta dwindled after like the 20 streak mark)

So the most glaring problem you'll notice with this team is Earthquake, it really comes down to luck when you're forced against it.
For the most part Oranguru will mostly only spam Instruct and Trick Room as there's generally no reason to use Psychic, but don't get me completely wrong there were situations where it actually had to attack.
Crazy evening.
