I could not find the old thread about this so here it goes.

On a Vic II can add a blue dice to my attack pool on any rebel ship other than the Pelta or wingless MC80s?

the card is about the set speed of the ships, not the maximum. So for example, if your vic at speed 2 was attacking a CR 90 at speed 1 it couldn't add a die. However if it was at speed 1 attacking a pelta at speed 2 it could add a die.
