Scyther

Even though Scyther boasts the same Base Stat Total as its evolution, Scizor, a simple retype has set the two eons apart. While Scizor has been consistently vying for top spot in OU, Scyther is forced to dwell in its shadows. This leaves Scyther relegated to the RU metagame, where it can function as a good sweeper with Swords Dance to set up or Baton Pass its boosts to a teammate, thanks to its solid 105 Speed and 110 Attack in tandem with Technician boosted Aerial Ace and Bug Bite, allowing it to take down a fair number of threats in RU. Additionally, it can function as a scout with its access to U-turn in order to maintain momentum. However, Scyther possesses a severe weakness to Stealth Rock, mandating that it be used in tandem with a Rapid Spin user. Furthermore, it also faces competition from Scolipede and Durant, both of which are faster than Scyther, possess better type combinations, and have stronger offensive movepools. While Scyther is still a solidly viable Pokemon, you need to be sure it is exactly what you are looking for.
