As stated up there in my comment, Heatran is an ideal counter to Clefable. Standard Clefable sets have nothing to hit it. All you really need to do is keep it relatively healthy and you can stop Clefable easily. I suggest Heatran over other Steel types, and there is two reasons for this. The first is its Fire immunity, as most good Clefable sets run Flamethrower.
Definition. The genitive is the case (or function) of an inflected form of a noun or pronoun showing ownership, measurement, association, or source. Adjective: genitival. The suffix -'s on nouns is a marker of genitive case in English.
This document provides detailed information about the use of the Greek genitive case. However, it does not discuss the case endings or inflections of nouns, pronouns, articles, adjectives and participles. For information about the genitive case endings, see the document The Greek Article and Case Endings. The Greek construction of these kernels is basically: HEAD NOUN + GENITIVE NOUN (abbreviated as N-Ng, which stands for a N oun [of any case] followed by a N oun of the g enitive case). 2  Whenever we see this construction, we need to unpack it.
