Quiver Dance
Lilligant (F) @ Life Orb
Trait: Chlorophyll / Own Tempo
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Sleep Powder
- Quiver Dance
- Giga Drain / Petal Dance
- Hidden Power [Rock] / Hidden Power [Ground]

*At +1, has a Mediocre Special Defense, but a great 478 SpAtk and 457 Speed.
*Sleep Powder allows for setting up
*Max Speed at +1 allows outspeeding of scarfers such as Rotom-H (Hp Rock Kills at +1 After SR, Otherwise you can sleep Powder and hope to get more boosts)
*HP Rock Hits Noivern (Second Most Used Mon), Rotom-H, Rotom-C, Xatu, Sigilyph, Swellow, Scyther, Venomoth, Vivillon, Fletchinder and Ariados, all above 2% usage, which HP Ground does not
*HP Ground hits Magneton (Top Used Mon), Dragalge, Ferroseed (Neutrally, but it 4x resists Giga Drain), Drapion and Klinklang, which HP Rock doesn't. Choose based upon your teams Offensive coverage.
*HP Fire can be used to hit other grass types, steels and bugs.
*Chlorphyll gives it doubled speed in the off chance the enemy runs the uncommon Sun playstyle, while Own Temp stops Confuse Ray abusers and the confusion from Petal Dance.
*Giga Drain hits many Pokemon either super effectively or neutrall, and regains health lost from the Life Orb, but a more powerful Petal Dance can be used with Own Tempo.
*Life Orb can be replaced by leftovers at the cost of lots of power.

OO
*Healing Wish
*Dream Eater

C&C
*Scarf Typhlosion/Pyroar still outspeeds at +1
*Amoongus/Vileplume can usually switch in and hit it with a Poison move
*Due to its lack of bulk, most mons with priority can kill it, abusing sleep clause after a switch: Hitmontop, Druddigon, Kangaskhan, Gourgeist-XL, Kecleon, Hariyama, Ambipom and Zangoose aren't weak to any of its moves
*Grass Mons destroy the Sleep Powder/QD combo (Virizion, Exeggutor, Amoongus, Vileplume, Gourgeist-XL, Ferroseed)
*Scarf Scyther Outspeeds at +1
*Bulky Steel Mons Take out the HP Rock variant (Klinklang, Magneton)
*Ferroseed easily survives HP Ground, and Gyro Balls
*Fletchinder easily revenges with Gale Wings.
*Golbat can bulk anything Lilli throws at it and KO back with Brave Bird.

Synergy
Assuming you can only get +1 for definite, it needs SR to operate fully, giving it guarantee'd OHKOs. Being weak to Bug, Flying and Fire, a good Rock Type is decent synergy as it resists 2/3 of those, and to resist bug it has to be Rock/Flying, Rock/Fire or Rock/Fairy. Archeops, Magcargo and Carbink all fit these typing, and all 3 can learn Stealth Rock. Rotom-H resists all 3 weaknesses, too. Golem also works, as its 4x weaknesses are covered by Lilligant.

 

dont even mention possibility of choice set,

slash petal dance with giga drain prob which can be helpful with own tempo, remove mention of synthesis lilligant is frail and using it is basically wasting a turn as opponent attacks you. hp fire should be slashed or at least mentioned in set comments

fletchinder revengekills it 100% only fears hp rock. just say scarf scyther, doesn't matter if jolly or adamant it still outspeeds and kills lilligant at +1. golbat probably needs a mention, scarf pyroar could be mentioned with scarf typh

do other analyses even have synergy sections?

 

Most don't, but its p. handy. Editing now.

EDIT: Done.
