Right now, when you check a linked vanity item, you can only see the overworld sprite. It'd be nice to preview the "profile" look like when you're checking from gift shop or a store. Maybe do it for GTL too.
You could go for a Bulk Up or Leech Seed set with Careful nature. Something like this:
Breloom @ Toxic Orb
Ability: Poison Heal
EVs: 236 HP / 212 SpD / 60 Spe
Careful Nature
- Bulk Up
- Spore
- Drain Punch
- Seed Bomb
With a more optimized EV spread.
