Wdf are you talking about? That's wrong in like 8 different ways. Close Combat is what gives Gallade utility outside of the lead position. Take that away and Gallade is no better than a Dunsparce lead. So what if Gallade takes on a couple of SDef drops, LO recoil means that it's going to live long anyway. You're really better off running Close Combat to nail Tyranitar and Kingdra for OHKO's and for that matter, Swords Dance > Zen Headbutt in order to make Gallade, erm, a threat.
Zen Headbutt, CC, Leaf Blade, Shadow Sneak;
Kills off prominent leads most of the time.
Against the mentioned Steel leads mentioned here except for Heatran, CC doesn't cut it.
Also, I don't see why LO is needed. Lead Gallade should be using Focus Sash.
LO + HP EV's is just contradicting itself, really. Enough Speed EV's should be used to outrun Jolly TTar in order to give it utility outside of the Lead Position (as you said) and whatever's leftover in HP. @Focus Sash > @LO.
Gliscor leads, not really common.
and does Ice Punch even OHKO opposing Dragonite leads?
Oh, and this post wasn't directed completely towards you, I just felt like quoting this post for some reason xD
