Just a note on your sig, as funny as that T_S part is....When doing calcs were you taking into account that Selfdestruct and Explosion damage is calculated by halving the targets defense thus effectively cancelling out the resistance (there is no need to put resistances for SD and Explosion in since lib forge's calc doesnt take this halving of def into account, so leaving out the resistance manually is needed to gauge accurate calcs)? (Metalkids does actually take it into account, but thats besides the point since its off by like 1% lol)
607 Atk vs 416 Def & 334 HP (250 Base Power): 261 - 308 (78.14% - 92.22%) <-- Adamant CB Metagross Explosion VS Max hp /max def impish skarm
525 Atk vs 416 Def & 334 HP (200 Base Power): 271 - 321 (81.14% - 96.11%) <-- Max Att CB Lax Selfdestruct vs Max hp /max def impish skarm.
Done with lib forge's calc ^(yes they have been checked by more than one person). Not a exact OHKO but with sr is pretty much is.
