Slowbro @ Leftovers Bold Nature Regenerator 252 HP, 252 Def. Scald Psyshock Toxic Slack Off Slowbro makes a great Physical wall. 100/110/80 Defenses make Slowbro a tough nut to crack, and with access to instant recovery and Regenerator, Slowbro is tough to crack. Chandelure @ Choice Scarf Timid Nature Flash Fire 252 Sp. Att, 252 Speed Fire Blast Shadow Ball Energy Ball Trick Chandelure is here to do two things: Revenge kill, and cripple walls that want to switch in, such as Chansey. With a speed stat at 426 after Choice Scarf, Chandelure outspeeds most non-boosted Pokemon and can often OHKO. Rhyperior @ Leftovers Adamant Nature Solid Rock 252 HP, 252 Attack Stealth Rock Earthquake Rock Blast Dragon Tail Rhyperior is obviously for setting up Stealth Rocks, as well as dishing out damage to break Substitues with Rock Blast, or force out any Pokemon that wants to set up with Dragon Tail. Snorlax @ Leftovers Careful Nature Thick Fat 252 HP, 252 Sp. Def Curse Body Slam Crunch Rest With massive HP, great Sp. Def, and boostable Defense, Snorlax makes a great Special Wall capable of dishing out damage after a Curse or two. After Snorlax sets up, it can safely Rest without being able to be hurt much. Salamence @ Leftovers Jolly Nature Intimidate 252 Attack, 252 Speed Dragon Dance Dragon Claw Earthquake Aqua Tail This thing was Uber two generations ago, and in UU now? Might as well take advantage of it. Salamence can switch into a Physical Attacker and make it temporarily crippled with Intimidate, and then set up a Dragon Dance on the switch/weakened attack. Aqua Tail is there for Rhyperior, who is growing in popularity. Manectric @ Manecite Timid Nature Lightningrod 252 Sp. Att, 252 Speed Volt Switch Thunderbolt HP Ice Flamethrower Manectric is a great scout with 135 Base Speed and access to Volt Switch, and HP Ice and Flamethrower provide nice coverage. After a switch-in on an Electric Type attack, Mega Evolve, get the Intimidate, and take a free hit on whatever comes in.
