 This is the best Mew build to take on the 7-star Mew 2 Terrorite event when it drops in-game early next month. First, get your Mew Mystery Gift. Go on to Mystery Gifts and get with Code or Password. Input the Code, get your Mew. This event will run until the 18th of September. Next, train your Mew to level 100. Give it 17 HP ups, plus 2 HP Feathers for a total of 172 HP EVs, 25 Zinc plus 2 Clever Feathers for 252 Special Defense EVs, and 5 Corbos plus 2 Swift Feathers for 52 Speed EVs. Give it the moveset Amnesia, Nasty Plot, Acid Spray, and Dark Pulse. Amnesia and Nasty Plot are level-up moves and Acid Spray and Dark Pulse are TMs. Give Mew a modest nature mint. Hypertrain your Mew with bottle caps to max out its IVs. Head to Levincia to the Daily Bird Present Store, buy a Shellbell item and attach it to Mew, and finally head to Madali East to the restaurant and change Mew's Terotype to Dark using 50 Dark Terrashots, and there you have it.
