D actions on cards

Hello,

I would like to ask if D actions on cards are repeatable.

Example:

Vampire uses D action from card Smiling Jack The Anarch to burn it.

Vampire was blocked and action was unsuccesfull. This vampire unlocks somehow and wants to make this D action again, is it possible?

no

To give you a more detailled answer, I quote from the rulebook section 6.1.6, last paragraph:

A minion cannot perform each action via the same card in play (including from the minion's own card text) more than once each turn, even if he unlocks.
