Only one Critical Effect, to be specific. ACM takes the place of the standard critical effect, and so you cannot trigger this card and also deal a face-up damage card.
where is this indicated in the rules? the card doesnt indicate it replaces the normal critical effect?
Rules Reference, Page 4, "Critical Effects":
A critical effect, denoted by the “E:” header, can resolve if
there is at least one E icon in the attack pool.
• The attacker can resolve only one critical effect per
The standard critical effect is “E: If the defender is
dealt at least one damage card by this attack, deal the
first damage card faceup.”
Having abilities that grant critical effects merely expand the selection that you get to choose your one critical effect from.
