Damage Calculation

Gropser

Following scenario.

My opponent has Gallade-ex as his active pokemon, while having Lucario on his bench, granting him +20 Attack power for fighting type moves.

Gallades move does 70 +20 damage for each energy attached to my active Pokemon.

His attack should've done 130dmg if I'm not mistaken. 70 +40 for my energies and +20 from Lucarios ability. But he hit me for 150, one-shotting Mewtwo. So am I missing something or are the damage calculations bugged?

I assume Mewtwo only had 2 energies attached, and your opponent only had one Lucario in play?
