>>22573272What you're trying to do will never work, because you don't understand how different pokes affect different tiers.
All of the pokemon that are currently in BL would be S-Ranked or higher in UU, but their rankings in OU don't reflect that. (Salamence and Venemoth D; Zygarde and Smeargle C-, whereas Mega-Houndoom is ranked C in UU and B in OU). This happens because they are either outclassed in the tier they are banned to, or their checks/counters are common in their new tier, but rare in their usage-based tier.
Crobat is S-Ranked in UU because it checks a some threats, and defogs well. It's not ranked in OU because it is outclassed by other defoggers, and OU has a lot of faster-paced attackers that can OHKO it before it can do it's job.
tl;dr - S-rank UU=/=any rank OU (see salamence/venomoth)
