First full analysis, probably could have picked an easier pokemon than Celebi lol, but here we go. Big shoutout to StarGengar, who made most of this skeleton bit, I'll be moving this forward from here on. Thanks for any help! I'll get the write up going once I get some feedback.

--------------------------------------------------------------------
[Overview]
-Possibily the most versatile grass type, Celebi is capable of fitting many different roles (Wall, Sweeper, Supporter and Baton Passer), thanks to its wide movepool coupled with 100 base stats all around and reliable recovery
-Wide support movepool with Heal Bell, Thunder Wave, Dual Screens, Stealth Rock and U-Turn just to name a few.
-Access to Calm Mind, Swords Dance and the rare Nasty Plot make Celebi a fearsome, bulky set up sweeper, being also capable of Baton Passing those boosts
-Its grass typing, bulk and powerful attacks make Celebi a great check to bulky waters like Jellicent, Suicune and Vaporeon
-A total of 7 crippling weaknesses to very common attacking types, most notably to Ice, Fire, Dark and Bug attacks, with useful resistances to ground, water, fighting and electric attacks
-Faces serious competition with Virizion and Ferrothorn on most teams, both having more specialized stats and better defensive and offensive typing
-Benefits greatly from the boost given to Giga Drain this generation, although not much else has changed
[SET]
name: Nasty Plot Sweeper
move 1: Nasty Plot
move 2: Recover
move 3: Giga Drain
move 4: Earth Power / Psychic / Hidden Power Fire
item: Leftovers / Life Orb
nature: Modest
evs: 220 HP / 252 SpA / 36 Spe
[SET COMMENTS]
-100 base SpAtk and excellent bulk are just enough to make Celebi an effective Nasty Plot user
-With Giga Drain, Life Orb and Nasty Plot, Celebi will be healing large chunks of health just for attacking, nullifying the Life Orb recoil
-The last move is tricky, as if you choose Hidden Power Fire, you are walled by Heatran, but with Earth Power you lose to Skarmory and have a harder time with Ferrothorn.
-Different from Virizion because it sets up faster and has instant recovery, Recover helps set up against weak attackers
-Nice bulk + Recover makes it surprisingly tough to take down
-Outspeeds all unboosted Tyranitar even with Hidden Power Fire while maintaining excellent attacking power and bulk
[ADDITIONAL COMMENTS]
-Different coverage moves
-Celebi despises steel types like Ferrothorn, Heatran and Skarmory, as even if running the appropriate attack he can still lose to them (Balloon for example), making Pokemon like Conkeldurr and Heatran excellent partners to Celebi. Heatran also hates bulky waters, who Celebi handles well.
-Dragonite, Latias and Salamence can take Celebi´s attacks all day and set up on him, so bulky water types with Ice Beam like Suicune, and even Ice Shard users like Mamoswine make good teammates for Celebi. Water types also share good synergy with Celebi.
-Celebi resists most priority attacks, but has no way to boost its average speed, and faster sweepers (like Gengar and Hydreigon) often carry super effective attacks on Celebi, so is vital to take them out before attempting a sweep
- 4 HP / 252 SpA / 252 Spe without Recover for pure sweeper
[SET]
name: Tinkerbell
move 1: Leaf Storm
move 2: Thunder Wave
move 3: Hidden Power Fire / Earth Power / Psychic
move 4: Recover
item: Life Orb
nature: Modest
evs: 232 HP / 240 SpA / 36 Spe
[SET COMMENTS]
-This set combines Celebi´s support capabilities with his high offensive power
-Leaf Storm is your strongest attack, and will likely 2HKO anything that doesn´t resist it and is not named Blissey / Chansey
-Excellent at spreading paralysis to support slower teams with sweepers such as Conkeldurr or Scrafty
-Choice of coverage move, as with other sets, is choosing what you want to hit and need coverage for
-Recover for longevity
[ADDITIONAL COMMENTS]
-Hit and run attacker so entry hazards help it a lot
-Has coverage problems for an attacker, but many switch ins hate either being paralyzed or eating an attack, so good prediction is required
-New Team Preview really helps with this, as you can predict what your opponent's answer to Celebi will be, and either attack straight out or paralyze
[SET]
name: Defensive
move 1: Giga Drain / Grass Knot
move 2: Hidden Power Fire
move 3: Thunder Wave / Leech Seed
move 4: Recover
item: Leftovers
nature: Bold
evs: 252 HP / 220 Def / 36 Spe
[SET COMMENTS]
-With this set, Celebi has many ways of helping its teammates
-Thunder Wave makes slower and/or set up sweepers life easier (like Haxorus and Metagross), while Leech Seed will help Celebi and its teammates stick around with a little HP return
-Giga Drain further replenishes Celebi's health and the boost in power make it more viable, but Grass Knot is more reliable against foes such as Gyarados
-With 100 base in HP and both defenses, Celebi can easily do its jobs and Recover any damage taken
[ADDITIONAL COMMENTS]
-The evs listed are for maximizing Celebi´s physical walling capabilities, and 36 Spe evs are needed to outspeed Jolly Tyranitar by 1 point (without Hidden Power Fire you can use 32 Speed evs)
-Again, many viable coverage moves are available. Hidden Power Fire is recommended because Ferrothorn is keen to switch in and set up Spikes. Hidden Power Ice is very good for Landorus, Dragonite and Salamence. Earth Power bashes Heatran and Excadrill. Psychic even earns a mention for being good against Fighting types
-Heal Bell can be used instead of your support move to heal status from your team, Perish Song for win condition
-Once half of your opponent´s team is paralyzed, slow, bulky sweepers like Metagross, Tyranitar and Scrafty will have an easy time setting up and sweeping
-Heatran and Gyarados make great teammates to this Celebi, as they appreciate the slowed pace. With them together you also create a pretty solid fire/water/grass core.
[SET]
name: Choice
move 1: Leaf Storm
move 2: Earth Power
move 3: Hidden Power Fire / Hidden Power Ice
move 4: Trick / Psychic
item: Choice Specs / Choice Scarf
nature: Timid
evs: 4 HP / 252 SpA / 252 Spe
[SET COMMENTS]
-With Choice Specs, Celebi will do immense damage with Leaf Storm (which has the same power as a Draco Meteor), denting any switch-in even if resisted
-As an advantage to other Choiced attackers like Hydreigon, Celebi can Trick his item on a wall (like Blissey and Ferrothorn) to severely cripple it.
-Coverage attacks for any of Fighting types, Steel types, Dragons / Landorus etc.
[ADDITIONAL COMMENTS]
-When using any Choice item, always run a Timid nature to either tie with base 100 speed pokemon when using Specs, and to outspeed Scarf Hydreigon when using a Scarf, and at worst tie with other base 100 speed scarfers such as Jirachi.
-While most Ferrothorn, Skarmory and Bronzong hate being Tricked with a Choice item, they will be a problem if you want Celebi to sweep, so fire types like Heatran and Rotom-H that can take out them are really appreciated.
-If you have HP Fire, you will have no options to hit dragon types (mainly Latias, Latios, Salamence and Hydreigon), making Weavile and Mamoswine great partners for Celebi, as both can sweep a weakened team with their high attack and priority in Ice Shard (hovewere be warry that they share a fire weakness with Celebi). Bulky waters like Suicune and Vaporeon can also be good partners to Celebi, as they tend to carry Ice Beam and have a good type synergy with him.
-Baton Pass / U-turn for scouting
[TEAM OPTIONS]
-Important to remember type synergy with Celebi unique resistances and weaknesses
-Fire types, Water Types, and Dragon types all synergize well with Celebi
-Examples include Heatran, Gyrados, and Hydreigon
-Both defensive and offensive sets really appreciate entry hazards
[Optional Changes]
-Trick Room is a decent option, even though Celebi is fast, because it can set up the Trick Room, take the next hit, and then U-turn into your Trick Room sweeper
-Baton Pass, but outclassed by Mew mostly
-Swords Dance is generally inferior to Nasty Plot because of Celebi's limited physical movepool, and really should be only used on Baton Pass sets
-Celebi gets Stealth Rock, and usually has a moveslot that can be dedicated to a support move, but there are more productive things Celebi can be doing
-Celebi is able to set up Dual Screens reliably, and even gets Healing Wish to rejuvenate an injured sweeper
-Heal Bell works very well on more defensive sets in place of your support move, Perish Song for phazing and win condition
[Counters]
-Celebi can be handled by an assortment of different Pokemon, but they must take care upon switching in for fear of being paralyzed or hit with an approprite coverage move.
-Steels / Flyers / Fires / Ghosts / Darks / Dragons all fare pretty well - examples like Skarmory / Tornadus / Heatran / Gengar / Scrafty / Latios
-Reuniclus doesn't really care about Celebi, but needs Shadow Ball or Calm Mind to retaliate effectively (Ironically, Perish Song Celebi is one of the best counters for standard CM Reuniclus)
-Wobbofett usually means game over for Celebi if it isn't packing Baton Pass or U-turn
[Dream World]
-Celebi does not a special Dream World Ability
