<p>Offensive Tangrowth is typically seen as a physical booster with Swords Dance. But a base Although Tangrowth’s base 50 Speed would appear to make sweeping with him nearly impossible, it is easily remedied with Sunny Day support. Thanks to Tangrowth’s Chlorophyll ability, his Speed doubles in the sun, allowing him to outspeed almost all of the UU tier and take advantage of his high attacking stats, if only for eight turns (provided the Sunny Day user is holding Heat Rock). can make a sweep hard, and while Sunny Day alleviates this issue, the mere five (or eight with Heat Rock) turns of sunlight make set-up hard to accomplish without running out of time to sweep. However,While offensive Tangrowth is typically seen as a physical attacker with Swords Dance, this Tangrowth set attempts to use Chlorophyll to its fullest, by abusing the higher of Tangrowth's attacking stats, its Special Attack. While somewhat overshadowed by the physical sets, it's still a simple and effective set to use. Once a teammate sets up Sunny Day, Tangrowth can come in. He's easy to switch in, as his base 125 Defense allows him to switch into most un-boosted/neutralphysical attacks with ease.</p>
 
<p>Since this Tangrowth relies on the Speed boost from Chlorophyll to be successful, Sunny Day support is absolutely mandatory for him to function. Once sun is set up, Sleep Powder is generally the first thing that you'll want to Tangrowth should use, as most players will immediately switch in their Grass-type counter, allowing Tangrowth to quickly incapacitate it have a Grass counter they'll switch in, which is necessary to eliminate. With a sleeping his counter asleep and his Speed doubled, Tangrowth can use his flawless coverage to hit most Pokemon in the UU tier for heavy damage. Power Whip is used as a last-ditch stop to things such as Chansey. It provides no extra coverage, so it can end up being very situational. However, it prevents Tangrowth from being walled, and is therefore worth consideration. Modest is the nature of choice if Power Whip is not chosen, while Rash is the best option with Power Whip.SolarBeam is a very potent attack, and only takes one turn to execute in the sun which is one-turn in Sunny Day conditions. Hidden Power Fire gets a 1.5x power boost from sunlight, and AncientPower provides near flawless coverage, even without Hidden Power Fire (though Tangrowth would want should run Hidden Power Rock if it does not have Hidden Power Fire in that case). Power Whip is may be used over either Sleep Powder or Hidden Power Fire as a last-ditch stop to things special walls who would otherwise wall Tangrowth, such as Chansey. It provides no extra coverage, so it can end up being very situational. However, it prevents Tangrowth from being walled by certain threats, and is therefore worth consideration. The given EV spread and a Modest nature should be used without Power Whip, while an alternate EV spread of 32 Atk / 252 SpA / 224 Spe with a Rash nature should be used if Tangrowth is running Power Whip Modest is the nature of choice if Power Whip is not chosen, while Rash is the best option with Power Whip. </p>
 
[ADDITIONAL COMMENTS]
 
<p>Some damage calculations that demonstrate how Tangrowth deals with some common switch-ins:</p>
 
<ul class="damage_calculation">
 
<li>AncientPower vs. 120 HP/0 SpD Arcanine: 57.4%-67.8%</li>
<li>AncientPower vs. 0 HP/4 SpD Altaria: 54.3%-64.6%</li>
<li>AncientPower vs. 0 HP/4 SpD Houndoom: 68.7%-81.1%</li>
<li>AncientPower vs. 248 HP/0 SpD Moltres: 100.3%-118%</li>
<li>AncientPower vs. 224 HP/0 SpD Scyther: 142.3%-168%</li>
<li>AncientPower vs. 0 HP/4 SpD Swellow: 109.6%-129.5%</li>
<li>Power Whip vs. 0 HP/252 SpD Chansey: 58.5%-69%</li>
</ul>
 
<p>Conveniently, these many common Tangrowth counters are weak to Rock-type attacks, and meaning that they are OHKOed or 2HKOed by AncientPower; if Tangrowth can catch these Pokemon on the switch, he guarantees that they will be unable to touch him. Chansey is included, as it is due to beingarguably the best special wall in UU. Butit's However, she is easily 2HKOed by Power Whip as well. This set may not be able to boost up like a Swords Dance set, but with that comes the ability to it can hit hard off the bat and does not have to worry about having to set up again each time it switches switch in and out without having to set up each time. Also, proper team support is necessary for this Tangrowth to function. First and foremost is Sunny Day.</p>
 
<p>The EV spread is a jack-of-all-trades, attempting to do many things at once. The Atk EVs ensure a 2HKO on Chansey with Power Whip, while the SpA EVs ensure OHKOes on things such as Moltres, Scyther, and Swellow. See the damage calcs above for more info. The Spe EVs allow Tangrowth to outrun Jolly Swellow in Sunny Day conditions. An alternate spread of 8 Atk / 252 SpA / 248 Spe allows Tangrowth to out-speed Jolly Rhyperior and net an almost certain KO with Power Whip before Rhyperior can use Megahorn on Tangrowth. This spread still manages to 2HKO Chansey. However, Rhyperior is out-sped in Sunny Day anyway and is the only notable reason to use this spread.</p>(this paragraph is really really messy and kind of hard to decipher, so I decided to just rewrite it. Also, that alternate EV spread doesn’t merit a mention in my opinion as a QC member, as it is so situational.)
 
 
<p>The EV spread is fairly simple and straightforward. First, Special Attack is maxed out in order to let Tangrowth hit as hard as possible. Then, 224 Speed EVs are used, allowing Tangrowth to outspeed Jolly Swellow, the fastest non-Choice Scarfed Pokemon in UU, under the sun. The remaining EVs are then put in HP to give Tangrowth a bit of extra bulk. In the alternative EV spread, a Rash nature and 32 Attack EVs ensure that Tangrowth can 2HKO on Chansey with Power Whip.</p> 
 
<p>As far as offensive teammates go, it's hard to beat aPhysical Life Orb Arcanine. Not only does he resist /immune to Tangrowth's Fire-, Bug-, and Ice-type weaknesses, but he is also capable of taking advantage of the Sunny Day sun support that this Tangrowth loves. A STAB Flare Blitz in the sun will easily handle Registeel and Venusaur, whom this set has trouble with. Lastly, his physical attacking prowess compliments the special attacking power of Tangrowth. Houndoom works similarly, but tends to be specially based, being and is walledby Chansey (who also walls Tangrowth without Power Whip). However, Houndoom's access to Nasty Plot compensates for this, allowing him to break through almost any special wall. Blaziken also fits nicely on a team with Tangrowth, for much the same reason as Arcanine. Fire-types have an additional bonus in that tend to work especially well with Tangrowth, as they can counter some of the very few Pokemon who can wall this Tangrowth. For instance, Venusaur and Registeel are arguably the biggest defensive threats to this set, but both are KOed by a STAB, Sunny Day-boosted Flare Blitz or Flamethrower from any of the aforementioned Fire-types.</p>
 
<p>While Fire-types work well offensively, astandard Registeel may well be the best defensive choice for a partner. Registeel can paralyze enemies with Thunder Wave, which helps when Sunny Day runs out,. He canset up Stealth Rock (a necessity for any sweeper), and set up the crucial Sunny Day for this set. Registeel can also use Explosion to take out a counter whom Tangrowth missed. Registeel is either resistant or immune to the Ice-, Bug-, Flying-, and Poison-type attacks that plague Tangrowth, allowing it to easily switch in if Tangrowth is in danger of being KOed. However, you must beware of Tangrowth’s and Registeel’s shared weakness to Fire-type attacks. Chansey makes another good partner, having phenomenal special bulk to go with Tangrowth's excellent physical bulk. She can do all of the same things as Registeel (minus Explosion), but lacks type synergy with Tangrowth. However, Chansey does have the ability to wall Nasty Plot Houndoom, who can pose a significant threat to this set.</p>
