Can Tera and Mega Evolution/Z-moves be used on the same Pokemon in National Dex?

I don’t play National Dex so I don’t know. :/

You cannot Mega Evolve and Terastallize on the same Pokemon. To test this, use the following set in a battle:

test (Diancie) @ DianciteAbility: Clear BodyTera Type: RockEVs: 252 Atk / 4 SpD / 252 SpeJolly Nature- Diamond Storm

You cannot use a Z-Move and Terastallize on the same Pokemon, even if you have consumed your Z-Move. To test this, use this set:

test (Diancie) @ Rockium ZAbility: Clear BodyTera Type: RockEVs: 252 Atk / 4 SpD / 252 SpeJolly Nature- Diamond Storm

You may Terastallize if you hold an item other than a Mega Stone or Z-Crystal. Use this set:

test (Diancie) @ LeftoversAbility: Clear BodyTera Type: RockEVs: 252 Atk / 4 SpD / 252 SpeJolly Nature- Diamond Storm

And of course, you can’t use Mega Evolution and a Z-Move on the same set. No, not even with Rayquaza. Test with:

test (Rayquaza) @ Flyinium ZAbility: Air LockTera Type: DragonEVs: 252 HP / 252 SpeJolly Nature- Dragon Ascent

No.I tested this out on Showdown, and when you Mega Evolve, you cannot Terastallize. I have no idea why it doesn’t work, and most obviously, you stillcannot use a Z-move while Mega Evolved even in National Dex.

All of the three cannot be used simultaneously, however youcanuse a Z-move while Terastallized.
