Even though there are better megas, M-Aggron is amazing at running through most of OU teams provided they lack a special attacker or you maintain momentum.
Heavy Slam let's you handle all fairies, Stone Edge will rape most Bugs and Flying types. It gets Dragon Tail and Sneaky Stones if you want to be that cunt too.
Or you could throw EQ on it as well.
RestTalk sets are risky because then you leave yourself open to the opponent sending out something that can rape M-Aggron, but Filter and losing that Rock-weakness is key to helping M-Aggron as opposed to Aggron.
