Since these are print and play cards, does anyone have a BatB template for printing on the back of them?

I disagree, as that would seem to violate the normal order of giving action tokens: Double Pounce grants a conditional free action that can only be used for a duo attack, this is analogous to most move and attack powers, such as charge or running shot. If the rules worked the way that you suggest, then you would rarely be able to push to use charge or running shot without taking your pushing damage between the movement and the free attack action.

Secondarily, recall that when a character makes a duo attack, it's actually taking two sequential free actions as a result of being given a power action.

For your analysis to be correct, it would seem the proper order of events would have to be: Declare Double Pounce, take a movement action, give Batman and Catwoman a token, then give them a Duo Attack as a free action. To the best of my knowledge this special power does not work this way (also, note that Batman and Catwoman have Double Pounce on clicks where they do not have willpower, and conceivably, playing in the manner suggested would cause them to push off Double Pounce before the Duo Attack could be resolved).

In fairness though, this is getting to be much more about that specific figure, and less about the feat in question, so perhaps this question is best moved to the rules forum.

Edit: Thread is here.

Hate to get off topic but:

Hawk/Dove duo?
I'm assuming this is in DC75th?
Did I miss this preview?

Uncommon from Crisis.

I guess you did miss this preview - by years.

(Defense) Avatars of Chaos and Order: Hawk and Dove can use Super Senses and Toughness.

And just tom point out if you have 1 action token, push to duo, and ko with the first attack you do not recieve an action token. Which not only allows you to avoid pushing damage but it also means you clear.

You could potentially attack every turn using this feat

Nice article but my venue bans feats so...unfortunately will never get a chance to use this.
