I have just notice that the wording for Meganium d and Deoxys d Delta reduction attack is worded different and changes the attack strenght and effect majorly.
Meg d:
during your opponents next turn, any damage done by attacks from defending pokemon is reduced by 30.
Deoxys d:
during your opponents next turn, any damage done to deoxys is reduced by 30.
Most of the time the strength of an attack increases by what stage it is.
Here it gets weaker.
I don't recall another attack named the same but having different effects.
Are we sure this is not a mistranslation?
