Yup. The mimic card that lets you copy another power is not the reason.
Think about it. If there is one Extra Head card, and you copy it, still nobody has more than one extra head. You would only need one die.
For similar reasons, this is why with the two Extra Head cards and mimic you don't need 3 green dice. If you posses them, you can't copy them.
