I was surprised when I didn't see this on site

[SET]
name: Trickster
move 1: Trick
move 2: Zen Headbutt
move 3: U-Turn / Explosion
move 4: Stealth Rock
item: Choice Scarf / Choice Band
ability: Levitate
nature: Jolly
evs: 4 HP/252 Atk/252 Spe
Why this set deserves to be on-site:
- Shuts down some of the top currently used leads while still getting Stealth Rock up
- Can be utilized late game as a revenge killer
- If player opts for U-Turn can scout early and mid game effectively
Additional Comments:
- Alternatively a special set can be used with Psychic over Zen Headbutt and Fire Blast over Explosion / U-Turn
- U-Turn is the preffered option as it allows you to scout the opponents team early on.
- Choice Band Zen Headbutt OHKOs Lead Machamp while Scarf fails to do so.
- Can work as a trick absorber mid game.
Teammates and Counters:
- Teammates: Vaporeon makes a great counter as Azelf will normally lose to Infernape (Fake Out + Fire Blast), Heatran (Unless you explode), and Ninjask (Assuming Vaporeon has Roar).
- Counters: As stated above Ninjask, Infernape, and Heatran are the main commonly used leads you need to worry about.

If need be I can post more in the Teammates and Counters section but I feel like this set is fairly obvious and being a lead it won't have much that should be countering it. Also It'd be helpful if others, assuming this set gets approved, could write up an analysis for it since my grammar is a bit off ha.
