The main special wall, as all we know, is Blissey, but it's over over over used. I was looking for other wall, and I found that in the D/P analysis: Snorlax move 1: Body Slam move 2: Earthquake / Crunch / Pursuit / Fire Blast move 3: Sleep Talk move 4: Rest item: Leftovers nature: Careful evs: 220HP / 36DEF / 252SPDEF It have problems with Steel types if it carries Crunch, with Ghost if Fire Blast and with Flying if Earthquake. But it can stand very well lots of Special Sweepers. Regice move 1: Ice Beam move 2: Rest move 3: Sleep Talk move 4: Thunderbolt / Toxic / Seismic Toss item: Leftovers nature: Calm evs: 252HP / 252DEF / 6SPD An Sleeptalker, the same as Snorlax, but it have better offensive capabilities, and with a 100 defense stat and 200 special defense stat it can stand a lot of hits, but it have problems with his weakness, and with Raikou if you choose Thunderbolt in the fourth slot. Ludicolo move 1: Rain Dance move 2: Surf/Energy Ball/Grass Knot/Giga Drain move 3: Ice beam move 4: Leech Seed item: Leftovers/Wet Rock ability: Swift Swim nature: Calm EVs: 204HP / 76SPATK / 124SPDEF / 104SPD It has good Special defense stat, and it can stand some strong hits, furthermore, if it's raining, it can OHKO Salamence, before it kills you with his Draco Meteor. The main trouble, is Heracross. I also thought about Mantine, but his 4x electric weakness is a big trouble. We should be more original. PD: Sorry for my horrible english xD Edit: A big bug in the comments of Snorlax.
