Why is nobody posting ;_;.
I tried Sub Swords Dance Terrakion a bit later after Poppy posted it and I can testify to its effectiveness at luring in BOTH of the spin blockers and swiftly eliminating both of them with a +2 Stone Edge. Terrakion can even set up Swords Dances in front of Giratina-a if it lacks Roar which lets it become a fantastic stall breaker, seeing that the other Great Wall, Lugia, is OHKOed by +2 Stone Edge.
Oh and if you run Salac Berry (Pocket I'm looking at you) you can even sweep teams unexpectedly! Its high base Speed coupled with a resistance to ExtremeSpeed makes it nearly impossible to revenge kill after the Speed boost (assuming it hasn't Close Combated yet) and nothing except Groudon likes tanking its +2 STAB moves.
Oh and its the only thing that can be a sure fire check to both Swords Dance and Dragon Dance Rayquaza if it runs a Choice Scarf. Its also hilarious seeing Scarf Terrakion used against Calm Mind Dark Arceus !_!, being able to revenge so many threats to Uber Stall makes it a really cool choice if you can find a way to put it on anywhere IMO.
Also again credits to Pocket for the fantastic Sub SD Salac Berry Terrakion set (he almost swept me with it !_! well then Stone Edge missed).
Choice Band is a fine lure if you think Roar Giratina-a is too common for 2HKOing Specially Defensive variants with Stone Edge after Stealth Rock also, but Stone Edge PP drops FAST. It also 2HKOes Groudon after a layer of Spikes if it thinks it can waltz in and absorb this blow.
(15:32) Dusk [DW Uber]: Actually Deoxys-a is not the frailest uber
(15:32) Dusk [DW Uber]:Its Carvanha
(15:33) X-Spin: O.O What are its bases?
(15:33) Dusk [DW Uber]: 45/20/20 so close to matching Deo-a's 50/20/20
(15:33) X-Spin: That's enough to wall Specs Kyogre!
Great Sage is the best.
