^Yes Scyther is amazing in Volt-turn teams! Volt-turn teams were especially good before Aerodactyl came into the tier, because Natu stopped the most common SR layers completely, which were Claydol and Uxie. Another wonderful member for a Volt-Turn team, and for Scyther, is Specs Rotom-C. Wonderful wallbreaker and stallbreaker which has amazing synergy with Scyther. And to complete the core, Scarf Moltres is a wonderful third partner to the Volt-turn combo, providing the team with a scarfer and Moltres covers some weakness that the other 2 pokes share, such as Fire. Of 'course with 2 4x SR weak pokes you are going to need rapid spin support and Natu support imo, along with some hazards, and you have a very annoying and effective team!
