Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I genuinely dislike Leech Seed and Synthesis because by definition Necturna can use any boosting move, and these allow it options like a fast SubSeed set or recovery along with a QD or Coil set. Even though Synthesis is somewhat limited it is still a strong functionality.
Also I think HeaL confused Worry Seed for Leech Seed when he said the moves were tutors. In general I think we should avoid giving Necturna options we discussed and opted against (blacklisted rather than not included), since it can get those options via Sketch.
Leech Seed was not brought up in this thread because it was a tutor move. I think people just brought it up as a grass move. I'm not saying that I agree with it personally, but a lot of people have supported it for whatever reason :/ If further discussion on it continues, I will reconsider banning it, as I already mentioned in my previous post.
To begin, I changed Horn Leech to an evo move to reflect the creators original intentions, and its original moveset. The move pattern, although already quite nice, was streamlined to a move every six levels with the exception of the first. Leech Seed and Night Shade were added to ease the tension on the beginning moves, and adds some weaker moves to the fray. Ominous Wind was moved to the Egg moves section because its flavor didn't really fit with the rest of the movepool. Finally, Phantom Force was added as a last move because of its power and distribution are usually quite late.
Giga Drain, Gravity, Pain Split, and Super Fang are already present in its moveset, so adding them here would be flavorful. Seed Bomb is outclassed by its other Grass moves, and relates slightly to Necturine. Snore is required. Spite works well for Necturna's distrust of humanity, and a possible motivation to harm them. Worry Seed is pretty much useless, and fits with the Grass Motif.
Ominous Wind was moved down here from level up, and Grassy Terrain maintains the Grass Motif.

Leech Life continues the trend of energy sapping shown through other parts of its moveset, and is mostly outclassed by other options. Sleep Talk changed numbers. Nature Power is great flavor and synergizes well with Grassy Terrain. Dark Pulse is already present on its moveset and Confide is required.
Cut
Flash
Secret Power
Telekinesis
Cut is an old HM while Flash, Secret Power, and Telekinesis are old TMs.
Removed Infestation because Perish Song + trapping is a very bad idea. Also removed Destiny Bond because it can take down mons super easily.
Added Grassy Terrain at level 45 and Phantom Force at Level 55, Changed Horn Leech to be learned upon evolving, as this what usually happened to the Pokemon that learns a move at the same level it evolves. The rest is unaltered.
-Leech Life is completely outclassed by Horn Leech, and fits with Necturna.
-Nature Power is standard for a Grass-type.
-Dark Pulse is learned by most Ghost-types, and it will never be used over Shadow Ball.
-Confide is required.

Well, this is the important part, as Necturna would gain a total of 17 tutor moves, with 11 new moves (13 if you count Dark Pulse and Sleep Talk, which I already included as TMs). While this number is pretty big, it's not unprecedented as Trevenant learns 13, Gourgeist 11, Gengar 18 and Duknoir 14, and this counting ORAS tutors only, where some moves like Dark Pulse and Sleep Talk weren't available.
Bug Bite: Wile this might seems out of place at first, it's already learned by carnivore plants like Victreebel and Carnivine, so I made Necturna follow this trend. Gastro Acid: Again, learned by Victreebel and Carnivine Skill Swap, Role Play and Spite are common for Ghost-types Worry Seed and Seed Bomb are standard for Grass-Types. Trick: Probably the only new move in this submission that could see competitive use, but it's limited to Choice Band sets, that could use it to cripple an otherwise safe switch-in once in a match. I decided to add it as it's applications are limited, so I believe it still within what a consistency update should do and it's learned by almost all Ghost-types.
Flash Secret Power
Telekinesis
Secret Power is required
Notable omissions: Leech Seed: Not allowing Leech Seed was made as a conscious decision, and I believe we should respect that Night Shade: Not all Ghost-Types learn this, so I don't see it as necessary. Magic Coat: I would have included this one, but the Tutor list was already bloated enough, so I decided against it, as some Ghost-types, like Gengar, Banette and Dusknoir can't learn it.
Necturna's Level Up pool is very small, and I wanted to preserve this as much as possible while also adding new moves. The Level Up movepool now follows a 5-6 pattern. This change is necessary to avoid the having a move at Level 31 or having a weird gap in the movepool because few Pokemon have an evolve move at the same level it evolves. Horn Leech is the evolve move, as Necturine evolves at Level 31 and doesn't learn Horn Leech; it's clear what the Prevo process wanted. Perhaps it's not the move flavorful move, but it's much more feasible for Necturna to use Horn Leech than Necturine, so I like it there. Maybe those spines on Necturna act as horns. All I intend from this is to uphold the prevo process's decision, which I agree with this time.
Nect's movepool has a lot of Ghost-type moves so I tried to spread them out as evenly as I could. Leer and Vine Whip remain Necturna's Level 1 moves. Shadow Sneak is a weaker move that should be learned first. Leech Seed is controversial, but I like its fit on Necturna. Magical Leaf is an intermediate Grass-type STAB move that appears on both Grass-types and a Ghost-type (Mismagius, which reminds me of Necturna). As a primary Grass-type, Necturna currently has very few Grass-type moves. Will-O-Wisp, Toxic Spikes, and Hex are all learned together because I see the gimmick!! see what DK was going for. I added Grassy Terrain at Level 34 mostly to space out Ghost-type moves, but it fits nicely there. Night Shade got displaced way up to Level 39. I'd rather it be in Egg Moves but the Egg Groups just don't work out. Pain Split, Shadow Ball, and Power Whip are the string of 10 level gap moves in Nect's current movepool, but I added Phantom Force as Necturna's capstone move. Thunder Fang, Poison Fang, and Super Fang remain Level 1 Heart Scale moves. Ominous Wind was moved to Egg Moves because really, there are too many Ghost-types in the Level Up pool imo.
Giga Drain was duplicated here from Egg Moves; Pain Split and Super Fang from Level Up. Spite and Worry Seed are generally useless but fit Necturna's design. Seed Bomb is outclassed by Leaf Blade.

Leech Life and Nature Power have great flavor. Sleep Talk and Confide are universal. If you run Dark Pulse over Shadow Ball you just need to go away.
Infestation is not added due to its interaction with Perish Song.
Cut (Gen 5 / Gen 6 HM01)
Secret Power (ORAS TM94)
Telekinesis (Gen 5 TM19)
Flash (Gen 5 / Gen 6 TM 70)
Cut is a transferrable HM, and Telekinesis, Secret Power, and Flash are old TMs.
Consider this your 18ish hour warning, looking good to see so many quality WIPs!
I also think I'm going to ban Infestation (and similar trapping moves), as a number of people have pointed out problems with its interaction with Perish Song. Tagging mxmts and G-Luke so that they have time to remove Infestation. Also tagging LucarioOfLegends and snake_rattler so that everyone can finish up their submissions and make final posts.
