Chatot @ Choice Specs 
/ Choice Scarf
Ability: Tangled Feet
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Boomburst
- Heat Wave
- Hidden Power (Ground) / Chatter / Tailwind / Defog
- U-turn
Chatot packs immense power in its STAB Boomburst, being able of tearing holes in teams left and right, but struggles to do anything at all to Ghost types with workable bulk, most notably Dusclops. It also struggles against a few things such as Soundproof users like Mr. Mime.

Liepard @ Black Glasses 
/ Choice Band
Ability: Limber
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Knock Off
- Pursuit
- Sucker Punch
- U-turn
Liepard pairs with Chatot to Pursuit trap many of the Pokemon that would otherwise interfere with Chatot's ability to freely use Boomburst. Because of U-Turn Chatot can lure in such Pokemon and then switch with Liepard in order to quickly neuter or remove an issue such as Dusclops or Misdreavus. Notably, 2 of the most significant Steel types in ZU are also Psychic type, which makes Liepard even more suited to partnering with Chatot. Liepard can also wear down or finish off Soundproof Pokemon such as Mr. Mime and Bouffalant for Chatot.
---Teambuilding Weaknesses---
A partner to prevent the opponent from carelessly using Volt Switch and something bulky enough to take a couple of attacks, particularly Fighting Type attacks, are very good additions to this core. Hazard removal is highly recommended because of the pivoting this core may do and the fact that Chatot is weak to Stealth Rock and taking additional Stealth Rock damage. This pair is also not particularly amazing at breaking defensive Probopass, so a partner that circumvents it could be helpful.
