I didn't want to post this core because I was actually pretty sure Mega Metagross was going to be banned. But this is something cool I used when testing out Tyrantrum.
Tyrantrum + Mega Metagross is a really fantastic wallbreaking duo. Tyrantrum with a Choice Band already hits insanely hard, with the only things that really stop it being Hippo and Chesnaught to an extent. As it turns out, Grass Knot Mega Metagross lures in Hippo very easiler, and also has little trouble with Chesnaught (although having an extra switch-in to it is recommended). Then, Celebi covers the weaknesses the core has, while also providing Substitute support. Metagross and Tyrantrum behind a substitute is no laughing matter. The biggest issue with both, I would say (but mostly Tyranitrum), is the ease with which it is revenge killed. But Substitute prevents that from being a factor. For the rest of the team, something to cover Landorus-I would probably be good for the rest of the team, as well as things like Charizard X and Wisp Talon. An additional check to Lati/Diancie/other based 110s would also be good. But the core in general is super fun and makes really good use of both Tyrantrum's and Metagross's best qualities.
