Relaxed nature. Loves to eat.
I suppose I'll post the lead Giratina-O set I use. Anyone who's been playing on the ubers ladder is probably farmiliar with it by now.
Giratina-O @ Plat. Orb
Adamant
252 ATK, 96 SPE, 160 SDEF
-Dragon Claw
-Shadow Sneak
-Will o Wisp
-Earthquake
I got really tired of Deoxys bombarding me with hazards, so I made this lead to deal with it. Deoxys will get off one hazard before it dies. This combo also deals with lead Mewtwo and Mew efficiently. Earthquake is there for Dialga leads, 2hkoing most of them (although offensive variants will ko you with Draco Meteor), and it helps my team deal with those random Heatran popping up lately. Will o Wisp is there for physical attackers that Giratina-O can't handle by herself (yes it's a girl). Since it lures in scizor like anything, crippling it also helps my Rayquaza and Darkari sweep. It also neuters Groudon (after a burn Dragon Claw is like a 5hko).
Adamant and max attack is used to guarantee that Dclaw and Shadow Sneak always finish more defensive Deoxys variants. The special defense EVs allow this to survive a surprising amount of punishment; for instance, Modest Scarf Orge's ice beam never 2hkos, and some uninvested Draco Meteors (such as from opposing physically-based mixed Giratina or from a devoted defensive Dialga) do not ohko. The speed EVs allow Giratina to outrun pretty much all of its base 90 brethern that are EV'd defensively, and also allows it to outrun defensive Jirachi, Manaphy, and other base 100s.
