Here is a rather strange but effective Lugia set I have been using lately. I'll try and concise it with some other users later, but otherwise this just really needs grammar and spelling checks
[SET]
name: Offensive Calm Mind
move 1: Calm Mind
move 2: Aeroblast
move 3: Roost
move 4: Earth Power / Thunder / Hidden Power Fighting
item: Life Orb
nature: Timid
evs: 4 HP / 252 SpA / 252 Spe
[SET COMMENTS]
<p>This set takes a radically different approach from the other Lugia sets, focusing on Lugia's offensive capabilities instead of its defensive prowess. While Lugia's low base 90 Special Attack may seem unappealing, its bulk, Speed, and powerful Aeroblast more than make up for this setback.</p>
<p>Aeroblast is the crux of this set, being more powerful than a Life Orb-boosted Ice Beam from Mewtwo. With Stealth Rock, +1 Aeroblast 2HKOes Wobbuffet and nearly OHKOes Mewtwo, Lugia's most common counters. It can also 2HKO common threats, such as Giratina-O, Latios, Groudon, Scizor, and Forretress, as well as OHKOing Darkrai and Rayquaza after SR. In addition, it has a chance to 2HKO max HP Kyogre after Stealth Rock, though Calm Mind variants with Rest / Sleep Talk can cause trouble.</p>
<p>Roost is a vital move for this set, as it allows Lugia to set up multiple Calm Minds against specially offensive foes ,such as Palkia and Dialga. You should choose the last move depending on what your team can handle. Earth Power in general hits Pokemon who resist Aeroblast, such as Steel- or Electric-type Pokemon. Earth Power specifically helps deal with Dialga and Heatran, both of whom may attempt to wall Lugia. Thunder easily defeats Kyogre, opposing Lugia, and Skarmory. It also hits Ho-Oh, though be careful, as sun reduces Thunder's accuracy to 50% and allows Ho-Oh to OHKO Lugia with Sacred Fire. Hidden Power Fighting is a viable option, as it allows Lugia to 2HKO specially defensive Tyranitar after a boost, and OHKO minimum HP Tyranitar after Stealth Rock. While you will no longer 2HKO specially defensive Dialga (thus meaning that Lugia will lose to Bulk Up Dialga), Lugia will still be able to 2HKO max HP Dialga with a boosted Hidden Power Fighting. However, Hidden Power Fighting Lugia will have issues getting past Jirachi and Metagross. Finally, if Steel-types are not a problem, Ice Beam is a possibility to get a quick OHKO on Rayquaza and Garchomp while still 2HKOing opposing Lugia after you gain a boost. Ice Beam will also deal a massive amount of damage to Giratina-O.</p>

<li>Earth Power vs 4 HP Tyranitar 58.48% - 69.01%</li>
</ul>
<p>As you can seen from these damage calculations, this Lugia will greatly appreciate Stealth Rock, as it relies on that to defeat Wobbuffet and max HP Kyogre. Additional, Spikes are also fairly helpful due to them allowing Lugia to OHKO Mewtwo with a boosted Aeroblast.</p>
<p>An important thing to note about this Lugia is that due to its offensive nature, it has a radically different playstyle when compared to the defensive Lugia sets. Because of the lack of HP EVs, this Lugia will not be able to tank hits as well as the defensive sets. For example, an unboosted Outrage from Garchomp will 2HKO this Lugia after Stealth Rock damage. Offensive Lugia will often find time to set up after an opponent has KOed one of your Pokémon. For example, after Choice Scarf Palkia gets a kill with Spacial Rend, Lugia can set up. Lugia will also be able to set up on Choice Scarf Dialga's Dragon Pulses. Wobbuffet can be a very helpful teammate for Lugia, as it can Encore support moves and Earthquakes for Lugia to set up on.</p>
<p>There are several Pokémon who will be troublesome when attempting to sweep with Lugia. Blissey is by far the biggest problem, as she walls Lugia's entire moveset and can cripple it with status. Tyranitar is another serious issue. Lugia will have trouble even 2HKOing some Tyranitar with a boosted Earth Power, while Choice Band Tyranitar will usually OHKO Lugia with Crunch. Even worse, Tyranitar can actually trap Lugia with Pursuit. Without Thunder, Lugia will never 2HKO Ho-Oh without Stealth Rock, while Life Orb Ho-Oh will OHKO Lugia with Sacred Fire after Stealth Rock damage. While a +1 Aeroblast with Stealth Rock can 2HKO Latias, she can use Calm Mind and Recover to defeat Lugia in a Calm Mind war. In a similar manner, Rest + Sleep Talk Calm Mind users, such as Kyogre and Giratina, will be able to outstall Lugia. Without Thunder, Skarmory and opposing Lugia will have no problems phazing Lugia away with Whirlwind, or crippling it with Toxic. If you use Thunder over Earth Power, Dialga will wall Lugia.</p>
<p>Because of these issues, offensive Lugia works very well with the Tickle Wobbuffet + Pursuit strategy. Wobbuffet can use Tickle several times on Blissey, Lugia, and Calm Mind Giratina, and then let them fall prey to Pursuit users, such as Scizor, Metagross, and Tyranitar. You can also use Dugtrio with Wobbuffet to defeat Blissey after you have Encored her. Additionally, Pursuit users keep Latias at bay (provided that she doesn't have Hidden Power Fire in Scizor's case). Scizor can switch into Tyranitar's Crunch and threaten to do a massive amount of damage with Bullet Punch or U-turn. Ho-Oh unfortunately lacks any true counters; however, Kyogre can check it. Kyogre can also use Thunder Wave or Toxic to cripple Latias switch-ins, or even Waterfall to 2HKO Blissey (with Life Orb or Mystic Water). Groudon can easily force Tyranitar and Dialga out with Earthquake, and can make a great Skarmory lure with Overheat. Calm Mind Latias and Latios can defeat Kyogre, OHKO Skarmory with Thunder, and do a massive amount of damage to Tyranitar switch-ins with a boosted Grass Knot. Choice Scarf Palkia can lure in Tyranitar expecting Spacial Rend (only to 2HKO them with Surf), and can revenge kill Latias with Outrage. Mixed attackers, such as Dialga and Palkia, work well in dealing a massive amount of damage to Blissey. Dialga in particular can use Bulk Up on its mixed sets to lure in Skarmory. Bulk Up Dialga itself is also a great teammate, as it can set up on Blissey, Tyranitar, and Calm Mind Kyogre.</p>
