Galv works great with Gengar. Lay web, and dive to Gengar to block a spinner and set up a substitute if the opportunity presents itself. Galv also has serious teeth with his high speed and punishing Thunder in case your counter lead is TalonFlame (if you have a sash) or a defogger. Bug buzz will brutalize any magic bouncers who may seek to catch your web as well. Also being neutral to the automatic Ground type attacks people seek to dish at Electric types works great, especially if your attacker is not getting STAB from Ground attacks. Though sticky web's effectiveness against a slow bulky team with priority strikers (breloom, conkeldurr, scizor, metagross, etc) is minimal in my experience. He's a great addition to your team, but by no means should he be the only trick in your deck of six cards. However, his very presence should warrant at least one spinner or defogger on your team if speed is anywhere in your strategy.
