Cacturne
So I was really surprised to see that Cacturne's analysis lacks a defensive Spiker set. It has plenty of advantages over other Spikers, and has extra utility as a defensive poke with things like Encore/Leech Seed. I've used this to quite a bit of success on a few teams and it's pretty effective, especially under sandstorm.

[SET COMMENTS]
<p>While Cacturne is usually seen in an offensive role, it also functions fantastically as a defensive Spiker. Cacturne holds several advantages over fellow UU Spikes users; it's the only one with access to Encore, one of only two with instant recovery, and can be utilized under sandstorm to abuse Sand Veil. Its fantastic Special Attack stat also allows Cacturne to threaten most common Rapid Spinners with super effective Grass-type attacks. This set excels at laying down Spikes against many common Pokemon, such as Registeel, Spiritomb, Rotom, Milotic, and other bulky Water-types.</p>
<p>Synthesis provides recovery, allowing Cacturne to stick around longer and set up as many layers of Spikes as possible. Substitute should replace Synthesis if Cacturne is being used under sandstorm, since under those conditions Synthesis would recover only 25% health, while Substitute works well with Sand Veil. Encore is useful to lock opponents into a non-threatening move for more opportunities to lay down Spikes and prevents Cacturne from becoming set-up fodder. Leech Seed serves a similar purpose, allowing Cacturne to force switches and regain additional health. Energy Ball occupies the final slot as the best general attacking option, dealing heavy damage to all Rapid Spinners.</p>
[ADDITIONAL COMMENTS]
<p>As previously mentioned, this set can be used under sandstorm to abuse Sand Veil; if you choose to do so, then Hippopotas is a mandatory teammate, preferably in the lead position. BrightPowder can be the item of choice in this case, frustrating opponents even more by boosting Cacturne's already enhanced evasion. Grass Knot is a valid alternative to Energy Ball, hitting Pokemon like Milotic harder, as well as Rapid Spinners such as Claydol, Cloyster, and Donphan. Dark Pulse is another viable attacking option due to its great neutral coverage.</p>
<p>Hitmontop is easily the best counter to this set, as it can Rapid Spin away Spikes and OHKO with Close Combat. Since Spikes is the crux of this set, Ghost-types such as Mismagius, Rotom, or Spiritomb are necessary teammates to spinblock; they also provide an invaluable immunity to Fighting-type attacks. Cacturne's 4x weakness to Bug encourages opponents to attempt to gain momentum with U-turn users, the most notable of which is Scyther, who packs a punch, is immune to Spikes, and isn't bothered by Sand Veil thanks to Aerial Ace. Steel-types such as Registeel are recommended teammates as a result of this, and their resistances to the Ice-, Poison-, and Flying-type attacks that frighten Cacturne come in handy too. Finally, bulky Water-types pair well with Cacturne as they can sponge Fire-type attacks from the likes of Houndoom and Blaziken, who both resist Cacturne's STAB moves.</p>
