That's an interesting Volcarona set. It must be a nasty surprise when people expect the Quiver Dance set instead. I like the HP Rock suggestion--it'll give you better coverage and since you're going to be switching in and out anyways, you should have another Pokemon that can take on Heatran anyhow. Speaking of whom: Porygon2 @Eviolite Ability: Trace EVs: 228 HP/88 Defense/180 Sp. Attack/12 Sp. Defense Nature: Quiet -Recover -Hidden Power Fire -Thunderbolt -Ice Beam I honestly haven't played singles in a while because of VGC 2012, but when I did, I found this set to be surprisingly effective. Trace and BoltBeam allows Porygon2 to counter many major threats in the metagame such as Heatran but here's the real beauty of the set: HP Fire. You're probably wondering why I'm using HP Fire as opposed to Thunderwave like many other standard Porygon2 do. I originally ran Thunderwave but found myself getting Taunted almost every time I tried to use it. I also found that people love switching in Ferrothorn, Scizor and Forretress every time they saw it, so normally I used HP Fire on the switch in and followed up next turn for a KO. I've actually been wondering whether I should deliberately make the HP Fire have a BP of 60 so that if it Traces Scizor's Technician, it'll do even more damage to Scizor but that's very situational. The given EV spread is unusual, yes, since it's not purely defensive, but I've found that investing in Porygon2's Sp. Attack allows him to strike back and score major KO's for my team while sponging attacks thanks to Eviolite. This set also allows me to attack right through the predicted Taunts that Porygon2 always seem to attract. Heavily damaging the opponent with that fantastic coverage gives me room to use Recover when needed.
