[SET COMMENTS]
<p>Although Giratina is usually seen as a nearly impenetrable physical wall or sturdy Calm Minder, this set allows it to fulfill the role of an excellent anti-lead. The combination of powerful attacks, strong priority move, and Haban Berry makes Giratina one of the most reliable ways of defeating common leads such as Deoxys-S, Deoxys-A, Groudon, Mew, Rayquaza, Giratina-O, and Tyranitar. Draco Meteor followed by Shadow Sneak is a guaranteed KO on 252 HP / 4 Def Deoxys-S, limiting it to a maximum of one layer of entry hazards. Deoxys-A is defeated by the same combination of attacks, while Groudon and Mew will struggle to do any meaningful damage as Giratina chips away at their health with its attacks. Will-O-Wisp is immensely useful for burning Groudon, but Hidden Power Fire is also an option to defeat Forretress and Scizor provided that rain isn't present. Unlike Giratina-O, lead Giratina has the ability to defeat Rayquaza, and by extension, Giratina-O leads, thanks to Haban Berry. Finally, Aura Sphere 2HKOes 252 HP / 0 SpD Tyranitar, and gives Giratina a reliable way of damaging Dialga and Heatran. Due to Giratina's ability to outright defeat common leads, it is an excellent fit on just about any Ubers team.</p>
[ADDITIONAL COMMENTS]
<p>Despite its role as anti-lead, this Giratina also has a great deal of late-game potential. If Haban Berry isn't used up against your opponent's lead, it can be extremely useful in a pinch later on. For instance, Giratina takes less than 50% from Timid Lustrous Orb Palkia's Spacial Rend thanks to Haban Berry, allowing it to easily OHKO back with Draco Meteor. Shadow Sneak makes Giratina a great revenge killer, hitting many speedy threats like Mewtwo and Latios for super effective damage. Despite a Hasty nature, Giratina still possesses excellent bulk, and thank to Will-O-Wisp, it can still play the part of a physical wall if needed during the later stages of a match.</p>
<p>Most bulky leads that are not hit super effectively by Giratina's attacks will be problematic. Kyogre is probably the most threatening of them all, as it possesses the bulk to take repeated Draco Meteors and will easily defeat Giratina with Ice Beam. Barring Hidden Power Fire, Forretress doesn't take much from anything Giratina can throw at, Will-O-Wisp included, allowing it to comfortably set up Spikes against Giratina. Darkrai is also very threatening, as it can either choose to put Giratina to sleep with Dark Void or deal huge damage with Dark Pulse. Although almost never seen as a lead, Blissey fears none of Giratina's attacks, and can wither Giratina's health down since Giratina has no form of recovery. Pairing Giratina with a Choice Scarf Palkia gives it a reliable counter for Kyogre, as well as a way of OHKOing Forretress and Darkrai. Palkia also appreciates Giratina's ability to reduce the number of entry hazards that Deoxys-S sets up, as Spikes can quickly wear Palkia down. A mono-attacking Kyogre with Calm Mind will not only force Forretress out, but can absorb Darkrai's Dark Void while being able to set up against Blissey and defeat her. Kyogre also has the advantage of synergizing well with Giratina. Speaking of synergy, Scizor covers Giratina's weaknesses and vice-versa, capably sponging any Dragon-type attack that Giratina can't handle if it has consumed its Haban Berry.</p>
