comments: intersting set, tho u could get more healing w/ protect.  other sets to try out would be Unaware CM, consistin of Moonblast / Moonlight / Calm Mind / Flamethrower, or Moonblast / wish / Protect / Calm mind


Trevenant @ Sitrus Berry
Ability: Harvest
EVs: 252 HP / 252 Atk
Adamant Nature
- Shadow Claw
- Wood Hammer
- Rock Slide
Leech Seed - > Earthquake
comments:  if ur going for all out attacking, u might as well add earthquake to the set to round out coverage.  U might know of/want to try a more defensive set tho, consisting of Wisp/Seed/Sub/Attack of choice.  I’d also recomend trying out gourgeist small for a defensive grass/ghost seeder.

Talonflame @ Leftovers
Ability: Gale Wings
EVs: 252 HP / 252 Spd / 4 Atk -> 76 HP / 252 Atk / 4 Spd / 176 Spd
Jolly Nature -> Adamant Nature
- U-turn -> Brave Bird
- Taunt
- Will-O-Wisp
- Roost

comments:  176 speed gives him just enough to outspeed lead Max Spd Deo-D and taunt.  Brave Bird and Adamant Nature give him attacking presence as well as the utility of taunt/wisp/roost
Extra EV’s thrown into bulk for extra survivabiltiy/bulk

Latias (F) @ Choice Scarf
Ability: Levitate
EVs: 252 HP / 252 SAtk
Modest Nature
- Psyshock

Defog

comments: I’d recommend Latios here as he hits harder, and if ur going for trick/scarf ur obviously going for surprise and revenge killing, so the extra spA power might/would be nice imo
