I've been using a Cradily lead on my most recent UU team (still trying to achieve the requirements), and I must admit that it does its job extremely well. With its excellent overall bulk, it can survive many super effective and neutral assaults, set up Stealth Rock, and hit most common leads for great damage. Cradily is able to take out leads such as Moltres, Ambipom, Persian, Omastar, Froslass, Electrode, and more. Enjoy!

Cradily
[SET]
name: Life Orb Lead
move 1: Stealth Rock

nature: Adamant
evs: 228 HP / 176 Atk / 104 Spe
[SET COMMENTS]
<p>Cradily has been constantly seen as a bulky supporter Pokemon that is not very strong in the offensive department; however, this set attempts to take advantage of its ability to reliably set up Stealth Rock from its great overall bulk and the great dual typing it has to turn it into a solid, effective Stealth Rock lead. With a Life Orb attached, Cradily becomes surprisingly powerful, being able to 2HKO or OHKO almost every lead, such as Arcanine, Omastar, Froslass, and Cloyster, as well as becoming a decent late-game sweeper.</p>
<p>Even though Cradily has equal offensive stats, its physical movepool is much stronger than its special movepool; as such, Cradily's moveset is geared towards the physical side. Seed Bomb and Stone Edge are the two primary STAB moves, the former hitting Omastar and Kabutops for extreme damage, while the latter smashing Froslass and Moltres. Recover is used in the final slot to allow Cradily to heal any damage taken and lengthens Cradily's survivability during the match, especially since Life Orb's recoil will be reducing Cradily's health gradually.</p>
[ADDITIONAL COMMENTS]
<p>The suggested EV spread focuses primarily on Cradily's offensive stats, but leaves enough EVs to be used in HP so it doesn't become defensively weak and can still tank some hits. With 104 Speed EVs, Cradily is always able to outpace Omastar and 16 Speed Azumarill to smack them with a powerful STAB Seed Bomb. The 176 Attack EVs and Adamant nature give it a good chance at OHKOing the bulky Froslass and the previously mentioned Omastar, the former taking 92% - 100% from Stone Edge and the latter 91% - 100% from Seed Bomb. Finally, the rest of the EVs are added into HP so Cradily is never OHKOed by a Life Orbed Fire Blast from Timid Moltres, as it only does 63% - 75%, which gives you enough HP leftover to OHKO Moltres and not die from Life Orb recoil. Although rarer, Cradily is even able to survive a Life Orbed Fire Blast from Modest Moltres with enough HP left to survive Life Orb's recoil.</p>
<p>There are a few leads that Cradily has no chance at bypassing, most notably Uxie and Hariyama. With Uxie's high Defense stat and Hariyama's great HP stat and access to Close Combat, Cradily will have no chance at winning. For that reason, it's strongly suggested to use Pokemon that can handle the aforementioned threats. Due to Cradily being primarily used on bulky, offensive teams, Spiritomb is one of the best teammates for it. Spiritomb's immunity to Uxie's Psychic and Hariyama's Close Combat, as well as access to Calm Mind to set up against them, will easily threaten these two. Bulky Steel-types like Registeel and Steelix will also pose a big problem, as Cradily isn't strong enough to break through their massive Defense whatsoever. In this case, Water-types can work exceptionally well against these threats, particularly Milotic. To keep the bulky offense feel of your team, Milotic can run the Life Orb Tank set to hit very hard and still take neutral and resisted attacks to good effect.</p>
