Mega Aggron and Florges are done.
Mega Aggron
Type: Steel
Base Stats: 70 HP / 140 Atk / 230 Def / 60 SpA / 80 SpD / 50 Spd
Ability: Filter
Looking at Mega Aggrons stats, it has a lot going for it. A decent HP along with massive Defense and a great ability in Filter, cutting the power of all super effective moves by 3/4. While limited by not being able to hold Leftovers, it has excellent support moves such as Stealth Rock, Thunder Wave, and Roar. Due to its excellent stats and ability, Mega Aggron can act as a complete stop to Weavile, Florges, Aerodactyl, Crobat, Metagross, Roserade, and many other powerful threats in the UU metagame, due to its sheer bulk. Mega Aggron only needs 4 moveslots to work with, Iron Head, Earthquake or Thunder Wave, Roar, and Stealth Rock. Watch out for Mega Aggron, as it has the raw bulk to withstand nearly any physical attacker in the metagame while supporting its team.
Florges
Type: Fairy
Base Stats: 78 HP / 65 Atk / 68 Def / 112 SpA / 154 SpD / 75 Spd
Ability: Flower Veil / Symbiosis
Florges is one of the best special walls in the UU metagame. It has a massive Special Defense along with excellent support moves such as Wish, Aromatherapy, Rain Dance, Sunny Day, Safeguard, and Light Screen (though it lacks Reflect.) Most commonly seen running a set of Wish, Protect, Moonblast, and Aromatherapy, Florges is able to heal its teammates with Wish while healing status with Aromatherapy, and it still has a somewhat strong Moonblast, despite normally running no investment. Another key aspect of Florges is its mono-Fairy typing, granting it an immunity to Dragon and resistance to Dark, Fighting, and Bug, all very common types of attacks in UU. While its low physical Defense may seem like a very bad thing, it can still take almost any physical attack as a last resort due to typing alone, and any Steel-type can take care of its weaknesses while recieving Wish support from Florges. Be sure to bring a powerful wallbreaker capable of smashing through Florges, since you will see it often, and for good reason.
