Ability: Pressure
-Roost
-Reflect
-Light Screen
-Aeroblast, Ice Beam, or Toxic
This is Lugia's best wall set. Lugia is sometimes called "The Great Wall." This set utilizes Lugia's great defences. Roost is to recover from any entry, and battle damage. Reflect, and Light Screen are to make Lugia as bulky as possible so it can outstall any pokemon. The last slot is to deal some damage to your opponent. Toxic is probably your best bet at outstalling any wall, but if your using it to stop a sweep in it's tracks Aeroblast, or Ice Beam would be the better choice. Aeroblast can handle the commonly used Breloom, Heracross, Swampert, Weavile, and Scizor much better then Ice Beam. Ice Beam can handle the commonly used Dragons such as Salamence, Dragonite, and Flygon better then Aeroblast.
