I love Lugia but the fact is it is pretty shit when it comes to providing team support, like what Melee Mewtwo posted.

Arceus loses to Mewtwo with Aura Sphere, so it doesn't really wall it in rain unless you are Dark/Psychic Arceus. Lugia can still take +1 Ice Beam and survive, phaze Mewtwo out but at that point, Lugia will be near useless, anything else faster will kill it. Stealth Rock also hurts Lugia a lot but you have to remember Arceus hates Spikes and Toxic Spikes, both of which when added together does more damage than Stealth Rock.

Spikes immune is just a small advantage Lugia has over Arceus but Arceus does not attract Spikes users as much anyway. I won't say Lugia is simply garbage at the moment because it has some use, but your team has to be made to support it. Something to setup Spikes, Stealth Rock and although not necessary, Lugia will work much better with Rapid Spin support.

Lugia's typing has some use actually, it beats Calm Mind Grass, Fighting, Ground and Psychic Arceus with Toxic and Roost. Shaymin-S is stopped by Lugia as well. Arceus loses due to lower special bulk and neutrality to their STABs. The huge list of weakness blows but it also gives Lugia the ability to check Giratina-O better. Even Calm Mind Shadow Ball Giratina-O can struggle to get past Lugia if you are carrying your own Calm Mind or Multiscale. Dragon Tail Giratina-O will annoy Arceus much more than Lugia because of the Spikes weak Arceus has. Just saying Kabutops can't OHKO Lugia, assuming no boost

Lugia can also wall Latios lacking Thunder or not in the rain. Latias is walled the same way, while Dialga has trouble with Lugia unless it is raining and even that can be foiled by Roost. Any paralysis occurs and Lugia will likely lose. Palkia needs either Choice Specs/Lustrous Orb or Thunder in rain to beat Lugia, otherwise it too is walled. Arceus loses to even Scarf Surf in rain.

Speed Shuffler set is pretty reliant on luck, 66% isn't close to perfect and even Dragon Tail can miss lol. Also, Stealth Rock messes it up a lot, you lose reliable recovery, one of Lugia's greatest asset over Groudon/Giratina as a wall and Rest is a horrible way to recover when you have better choices available. Sleep Talk phazing is only great versus some stall teams who lack a wall to hurt Lugia but you will now lose to a lot more offensive pokemon.
