OU & NU Leader
Regieleki has no viable sets outside of the supportive ones. Every single team has an Electric immunity and Regieleki lacks the utility, bulk, or other characteristic that justifies using it. At best, it’s C rank. At worst, it’s entirely unviable when people realize Tapu Koko is oftentimes superior as a screens setter. Until then, it’ll hang on to a sliver of viability.
