haha currently elaborating
Options for Spinblockers: Ghostceus, Sableye, Giratina(-O)
1) Ghostceus loses to offensive spinners if they get to +2.
+2 252+ Atk Life Orb Excadrill Earthquake vs. 252 HP / 0 Def Arceus-Ghost: 409-484 (92.11 - 109%) -- guaranteed OHKO after Stealth Rock
+2 252+ Atk Life Orb Kabutops Waterfall vs. 252 HP / 0 Def Arceus-Ghost in rain: 438-516 (98.64 - 116.21%) -- guaranteed OHKO after Stealth Rock
2) Sableye is pretty unreliable as WoW only hits 75% of the time, plus if the opponent is a +2 offensive spinner, Sableye will survive up to 3 turns if it spams recover, including the burning turn.
3) Giratina-O > Giratina because Giratina-O is strong while Giratina just walls and that kills too much momentum, considering our team is of an offensive nature. Gira-O sits there being immune to Spikes and EQ, plus physical investment means it can take hits relatively well too.
I focus on physical walling, because it shares roughly the same resistances and weaknesses as Latios, having advantages only in taking Bug, Normal, Fighting and Poison attacks. Poison is non-existant in Ubers. Bug-type attacks are just Genesect’s U-turn which is physical. Normal-type is from EKiller and Wallceus only, who are physical too. Special Fighting-type moves are only from Mewtwo and Darkrai, both of which hit Gira-O SE anyway. 8 Spe allows me to outspeed Mixed Zekrom and other 4 Spe base 90s. Shadow Sneak because I want to limit Deoxys-S to one layer and Deoxys-A to one attack, plus revenge weakened Mewtwo. Outrage is to hit anything I like (general STAB) and Dragon Tail phases. I use EQ > WoW, because I need to hit Excadrill and WoW tends to miss, plus it allows me to beat SubSD Excadrill. I don't speed creep Tentacruel because imo that's a rare sight and 76 EVs is too much of a waste. It becomes much stronger with max attack, however if anyone disagrees I can change it.
