Hi Abe, great team and I ludvisc'd it. Also nominated it for the RMT archive. Anyways:
I played this on the ladder with a test team, and you seem to be weak to Scarfed Jirachi. It can cause major damage and resist Latios/Tyanitar/Shaymin. Also it can evade Magnezone and resist Frustration from Stoutland. Trick goes on Hippowdon as well.
I'll give a full rate later. Have a nice day.
