You could switch out the lead metagross with Hippowdon. That way you can set up sandstorm and rocks early plus you get another defensive beast. I'm not really sure if you want to keep the ScarfTar since Ape and Starf Scarmie are everywhere.
Yea, I know about the ground weakness, but I just planned on covering it with my two levitaters. And really putting ape in was my best option, that or I was thinking about azelf, but I lose the priority.
