Sceptile

Mega Sceptile has a unique set of perks over the tier's other Mega Evolutions that make it an effective revenge killer, cleaner, and offensive check to the tier's many Water- , Ground-, and Electric-types. Chief among these are its exceptional Special Attack and Speed stats, which enable it to threaten many offensive teams with its powerful STAB moves; its Grass / Dragon typing, which allows it to function as a decent check to Pokemon such as Suicune, Latias, and Hippowdon; and its ability in Lighting Rod, which makes it a uniquely potent offensive answer to Electric-types such as Mega Manectric and Zeraora. These traits make it quite an effective tool on offense against opposing offensive teams that lack a strong defensive presence and render it difficult to switch into consistently without a specially bulky Pokemon. That said, Mega Sceptile can nevertheless be quite easy to check both offensively and defensively. Choice Scarf users, strong priority attackers, Pursuit trappers, and the ubiquitous Mega Aerodactyl all exploit Mega Sceptile's frailty and common weaknesses, while most specially bulky Pokemon have the typing, natural bulk, or both required to switch into Mega Sceptile's attacks consistently. It is also helplessly walled by most of the tier's defensive Fairy-types, making it tough to use in the face of common threats such as Mega Altaria, Florges, and Togekiss. It also relies heavily on punishable moves in Leaf Storm, Focus Blast, and the very weak Hidden Power Fire to do significant damage and cannot fit all of its ideal coverage onto a single set, giving it a mild case of four-moveslot syndrome. This makes it tough to optimize for teams and relatively easy to position an offensive check against it. These setbacks leave Mega Sceptile quite helpless in a number of matchups despite its upsides and relatively awkward to fit onto teams due to both its numerous downsides compared to other Mega Evolutions and its covering of roles easily filled by other, non-Mega Pokemon.
