Comments

I would not use sucker punch on psychic terrain, but other than that, I love the yveltal! As for the kyogre, I will not change a thing! And for the amoonguss, do not understand focus sash.

---

The sucker punch was my mistake. I fixed the Yveltal set. As for Amoonguss's focus sash, I think it's there to prevent it from being one-shot by things like Groudon or Lunala so it can use spore on them more reliably.

---

Honestly, I would give Yveltal a hasty nature. Now I understand the Amoonguss!

---

If it had hasty, then it would take more damage from physical attacks. This Yveltal can't use any physical attacks (foul play doesn't count because it ignores the user's stats), so a timid nature would have almost no drawback. (except maybe less struggle damage, but I don't think that ever changes the outcome of a game)

I confuse timid and jolly a lot. I thought timid lowered special attack, but now I remember jolly does.
