Attacks » Agility
Does Fearow's Agility attack block Kangaskhan's Fetch?
Actually it does not; Fearow's Agility says stops damage done to Fearow, and the Fetch just draws a card. This is the new ruling from R&D.

Can I attack with a Pokémon if I just played it?

When I attack, do I discard the Energy card(s) I used to power the attack?
Energy is not used up by an attack. Unless that attack specifically says to discard an Energy, it stays attached to the Pokémon.
