Sceptile

Mega Sceptile can be extremely problematic for offensive teams due to its blisteringly high Speed and decent Special Attack. Mega Sceptile is the fastest Dragon-type in the tier, meaning it can easily revenge kill other Dragon-types, such as Garchomp, Latios, and Mega Charizard X, with Dragon Pulse. It also has a powerful STAB move in Seed Flare, which allows it to revenge kill fast threats such as Mega Manectric; Seed Flare in combination with Mega Sceptile's typing also allows it to easily deal with Water-types such as Rotom-W, Keldeo, and Slowbro. Another advantage its Grass typing brings is an immunity to Spore, which Mega Sceptile is also one the fastest users of. Furthermore, Lightning Rod also gives it an immunity to moves like Thundurus's Thunder Wave and Rotom-W's Volt Switch. However, due to its frailty, it is easily picked off by Choice Scarf users and priority moves, such as the common combination of Fake Out and Extreme Speed. This is compounded by its relatively bad defensive typing, which notably leaves it 4x weak to Ice Shard. It also doesn't have a very potent offensive typing and its strongest STAB move is widely resisted; thus, it often finds itself strained for coverage. Mega Sceptile also struggles against stall teams, as they tend to carry specific walls that Mega Sceptile cannot deal with easily.
