Forum:Alien grey

Does the effect that says "FLIP: Place 1 A-Counter on 1 face-up monster on your opponent's side of the field. (If a monster with an A-Counter battles an "Alien" monster, it loses 300 ATK and DEF for each A-Counter during damage calculation only.) After this card has been flipped face-up, when it is destroyed by battle and sent to the Graveyard, draw 1 card".

I have heard the if it is face down and attacked. The dwar 1 card effect does not activate.

Is this ture?
