Scyther

Scyther is a solid addition for momentum-focused teams due to its STAB U-turn and great Speed and Attack. Scyther's Technician-boosted Dual Wingbeats and Knock Off make it powerful in its own right, and its Flying typing and serviceable bulk let it pivot into many common threats. Knock Off cripples the longevity of many of its common checks such as Mudsdale, Diancie, and Talonflame, but Scyther itself is vulnerable to losing its item, which exposes its terrible Stealth Rock weakness and average bulk. Scyther is also weak to many Pokemon faster than it, such as Aerodactyl, Salazzle, and Choice Scarf Rotom-C.
