Electabuzz, a highly popular Underused Pokemon in RSE, received both a blessing and a curse in the transition to the DPP metagame - while it struggles to regain its old popularity in the Underused tier, it was blessed with an evolution, Electivire, who ascended the ranks into Overused. Pokemon whom Electabuzz once dominated entirely and Pokemon who didn't exist in RSE now compete with Electabuzz for a spot on a team, and Electabuzz simply does not have enough going for it to merit its old popularity. The most notable of the Pokemon who have crept out from Electabuzz's old shadow is Manectric, who is now blessed with an extended movepool and is almost always a far more usable choice. Despite this, Electabuzz is still a reasonably good mixed sweeper, and unlike Manectric, it is still able to defeat Chansey one-on-one. Though certainly not the best, it is definitely not the worst at its job and occupies its own unique niche in the metagame.
What sets Electabuzz apart from the crowd is its excellent Speed, which coupled with its acceptable offensive stats makes it an effective mixed late-game cleaner. Thunderbolt is the STAB move of choice, with good neutral coverage as well as useful super effective coverage on bulky Water-types. For the second moveslot, a Hidden Power of your choice can be employed in order to hit certain targets. With Hidden Power Grass, you can hit Pokemon who are immune to Electabuzz's STAB, such as Rhyperior, Lanturn, and Quagsire, super effectively, usually making it the best choice. Hidden Power Ice, on the other hand, achieves much more general coverage, with the combination of Thunderbolt + Hidden Power Ice hitting almost every Pokemon in the game for neutral damage.
Electabuzz suffers from being perpetually compared to Manectric on all counts since they share the same ability, same typing, same Speed, and similar movepools, though Manectric has slightly higher Special Attack to Electabuzz's slightly higher Attack. While Manectric is certainly a more accomplished special sweeper, Electabuzz has a number of moves that give it an advantage in certain situations. The most notable of these is Cross Chop, which with minimal investment 2HKOes standard 252 Defense Calm Chansey, who is the most prominent special sponge in UU and Manectric's greatest nemesis. If you run Hidden Power Ice, however, it may be worth your while to run Focus Blast, a stronger special attack that can OHKO Steelix and offensive Rhyperior. In the last slot, Psychic is necessary if you chose Hidden Power Grass in order to strike Venusaur, who otherwise walls Electabuzz. If you chose any other Hidden Power, then Substitute is an excellent choice to allow Electabuzz to scout, ease prediction on the switch, and avoid status afflictions.Team Options & Additional Comments >>>
On the special side, Discharge and Thunder are both alternatives to Thunderbolt as the STAB move of choice, with Discharge having lower raw power than Thunderbolt but a higher paralysis chance, and Thunder having more power, less accuracy, and the same paralysis chance as Discharge. Neither is wholly reliable, however, so Thunderbolt is usually the best choice. Focus Blast is another notable option for its ability to OHKO Steelix, but its low accuracy is a massive turn-off. Other moves that have some utility are those that catch some of the lesser seen special walls off-guard: Signal Beam hits Hypno, Uxie, and Grumpig for slightly more damage than a neutral Thunderbolt would.
On the physical side, one can employ a SubPunch strategy with Substitute and Focus Punch, allowing Electabuzz to 2HKO Registeel and OHKO Chansey. The only other physical moves of note, aside from Return, are the elemental punches. Each may be used as a coverage move or as an alternative to Hidden Power in certain situations. Toxic allows Electabuzz to hit bulky Pokemon such as Uxie and Spiritomb on the switch-in. Charge Beam can boost Electabuzz's Special Attack, but Charge Beam Electabuzz is pretty much entirely outclassed by Manectric. Lastly, Screech can allow Electabuzz to OHKO Chansey with Cross Chop.
Electabuzz's most indispensable asset is undoubtedly its Speed, and so it is almost always profitable to invest as much as possible in it. 252 Speed EVs and a Naive nature allows Electabuzz to outpace Timid 252 Speed Hidden Power Fighting Mismagius and tie with other positive-natured base 105s such as Scyther and Manectric. If you wish to invest more in other stats, 216 Speed EVs and a Naive nature allows Electabuzz to beat positive-natured base 100s such as Typhlosion. Next in order of importance are its offensive stats. The majority of EVs should be invested in the attacking stat you are focusing on, while you can divert some EVs to the other if you wish. When going mixed, remember that the most prominent special wall, Chansey, is 2HKOed by Cross Chop without any investment, and the most prominent physical wall, Steelix, is 2HKOed by Focus Blast without investment. Thus, not many EVs are needed to bypass common threats to solo stat sweepers. The more Electabuzz invests in its main attacking stat the better, for it is nowhere near as strong as some other popular mixed sweepers. Lastly, your HP stat should end in a 9 if you use Life Orb to minimize recoil damage.
Checks and Counters
Registeel is almost a complete stop to Electabuzz, easily shrugging off anything Electabuzz has to throw at it thanks to its titanic defenses. The best Electabuzz can muster is Cross Chop, which is not even guaranteed to 3HKO specially defensive variants. Steelix is more or less in the same boat, though it fears Hidden Power Fire and Focus Blast. Earthquake from Registeel or Steelix easily puts away Electabuzz for good. Uxie has great defensive stats as well, taking little damage from Signal Beam or Thunderbolt and hitting back with Thunder Wave or STAB Psychic. Rotom resists nearly everything from a standard mixed Electabuzz and can use STAB Shadow Ball, Thunder Wave, or Will-O-Wisp to cripple physical variants.
Ground- and Grass-types are immune to or resist Electabuzz's STAB attacks, and while they are often at risk of being hit by a super effective Hidden Power, those who are bulky enough to withstand one or two onslaughts make decent checks. Tangrowth and Donphan have high Defense and can take Ice Punch from physical Electabuzz, while specially defensive Venusaur can brush off Hidden Power Ice or Fire with Synthesis and hit back with its STAB moves. A special mention goes to Claydol, who resists all three entry hazards and has decent defensive stats, Rapid Spin, and STAB Earthquake. If Electabuzz lacks Hidden Power Grass, it is easily countered by Lanturn and Gastrodon.
Hypno and Grumpig both have high Special Defense and resist Cross Chop, making them excellent counters to Electabuzz. Keep in mind that Electabuzz is quite frail and easily revenge-killed, though there are not many Pokemon who are faster than it who are commonly used in UU. Swellow can revenge with Facade, but cannot risk switching into Thunderbolt. A special mention goes to Dugtrio, who is faster and can trap Electabuzz and kill it with STAB Earthquake.
