I mean, you could throw a z crystal in there

---

why would a z crystal be better than leftovers on rotom or choice specs/life orb on glaceon

---

I need a reason why.  You can't expect me to do that without a reason.

---

Isn’t Glaceon pretty bad in competitive?

---

What other pokemon do you have that you can use for the battle tree?

---

That I am willing to use:  I have Goodra, Gardevoir (not mega), Gyrados (mega), and Lucario (not mega, Physical sweeper).  Let me know if you want the sets for any of them.

This is only for the Battle Tree, not competitive.  Maybe an occasional Wi-Fi battle, but it is mostly for the Battle Tree.

Rotom Wash is fine. For the Glaceon, you could try and replace something with Hail. Usually this move sucks, but it works great with Glaceon's Ability Snow Cloak, which boosts its evasion by 20%. Additionally, you're now free to replace Ice Beam with Blizzard. And if you want, you can add Aurora Veil to decrease damage done to you.

Close Combat is really strong, but it lowers your defense and special defense. Replacing it with Brick Break means you deal less damage, but at least your stats aren't lowered. I'm more of a safe player, so I tend to avoid stat lowering moves.
Hope this helps :D.
