Hey C&C, this is the first set that I've decided to try and post and I think that it's a very underrated and potentially useful set that Arcanine can use.

<p>While Arcanine is usually seen as a sweeper because of his high Attack and Speed stats, he has all the necessary tools to function as an effective specially defensive tank. Arcanine's good HP and Defense, naturally high Attack and Speed, and access to a reliable recovery move, Morning Sun, allow him to safely switch into and beat many top-tier special sweepers one-on-one.</p>
<p>With maxed out HP and Special Defense stats, Arcanine becomes a formidable special tank. This Arcanine is able to switch into some of UU's strongest special attackers and eliminate them. Even with no investment in his Attack stat, Flare Blitz and ExtremeSpeed still hit hard enough to take care of physically frail sweepers such as Alakazam and Mismagius, as well as targets hit super effectively, such as Venusaur. Toxic is Arcanine's main source of damage against walls such as Milotic and bulkier sweepers such as Moltres; both of the aforementioned Pokemon can generally be stalled out with Morning Sun.</p>

<p>Here are some damage calculations that demonstrate Arcanine’s impressive special bulk:</p>
<h3>Damage Calculations</h3>
<ul class="damage_calculations">
<li>Timid 252 SpA Life Orb Alakazam Psychic: 43% - 50.8%</li>
<li>Timid 252 SpA Mismagius Shadow Ball: 24.5% - 29.2%</li>
<li>Timid 252 SpA Life Orb Venusaur Sludge Bomb: 34.6% - 40.9%</li>
<li>Modest 252 SpA Life Orb Moltres Air Slash: 36.7% - 43.2%</li>
<li>Timid 252 SpA Life Orb Houndoom Dark Pulse: 33.1% - 39.1%</li>
<li>Timid 252 SpA Life Orb Rotom Thunderbolt: 35.2% - 41.7%</li>
<li>Bold 0 SpA Milotic Surf: 44.3% - 53.1%</li>
</ul>
<p>With his special bulk, Arcanine can avoid being 2HKOed by the some of the strongest neutral special attacks UU has to offer, provided Stealth Rock is off the field. In return, Arcanine can 2HKO or Toxic stall each of these threats while recovering his health with Morning Sun. Arcanine also serves as an excellent lure for Milotic, whom he can Toxic and stall out with Morning Sun (unless Milotic has Toxic or Rest).</p>
<p>Rapid Spin support is extremely important for this Arcanine. Due to his Fire typing, Arcanine loses 25% of his health each time he switches into Stealth Rock. As a result, many of the sweepers who normally only 3HKO Arcanine are able to 2HKO him with Stealth Rock on the field. Arcanine also has problems with strong physical attackers, such as Rhyperior, Azumarill, Feraligatr, and Aggron. Thus, a physically defensive Blastoise makes a great partner since Blastoise can hit Rock- and Ground-types for super effective damage with Surf. Blastoise can also wall any physical Water-types who may otherwise cause Arcanine problems.</p>
<p>Other good teammates for this Arcanine include physical walls who can take strong Rock-, Ground-, and Water-type attacks. Leafeon, Torterra, Tangrowth, and Milotic are all excellent choices, especially since each of them has a reliable recovery move. Arcanine also dislikes any form of status, so a cleric is greatly appreciated. Thus, Leafeon is an ideal teammate; he has access to Heal Bell and, as previously mentioned, is an excellent physical wall.</p>
