From Bulbapedia page about Z-moves:well since only two people have posted and they're both decent sets, we need SOMEONE to win best meme
Snivy @ Grassium Z
Level: 5
Ability: Contrary
EVs: 240 SpA / 252 Spe
Timid Nature
- Leaf Storm
- Worry Seed
- Glare
- Hidden Power Ice
z-worry seed gives you +1 Spe which patches up Snivy's average Speed, letting it KO Staryu without fearing an Ice Beam. HP Ice hits other Grass-types. Glare can paralyze stuff that Mudbray is outsped by, allowing it to get the upper hand. Once Mudbray's checks have been eliminated it can come in safely enough.
edit: forgot about contrary. whatever just run overgrow.
Z-Moves based on status moves are enhanced versions of the original moves, having a Z- prefixed to the start of the status move's name. While they have the effects of the original status move, the user also receives the effect of Z-Power (Japanese: ZパワーZ-Power), which is executed before the move itself. For example, Z-Splash also boosts the user's Attack by 3 stages, while Z-Parting Shot also restores the switch-in ally's HP by 100%. These effects are not affected by Contrary, Simple, or Heal Block.
So this can actually work
