Ruling Mew (FCO) and Marshadow Gx

[pikachuuuu101]

Can I use mews ability to copy the attack of Marshadow GX copying the move from my discard pile. E.g: if i have a mew active with energy, and a Marshadow benched, can I use the attack of a Pikachu in my discard?

Marshadow doesn't gain the attacks of pokemon in the discard, it just has the option to use them. So no Mew won't have access to them
