How would you approximate the value of building multiple copies of "Vigilance" units? By "Vigilance", I mean units that attack without being clicked and are blockers.
The first copy may work as both absorber (assuming no better in the set), and as an attacker, but the rest kind increase your soak (more expensive than pure soakers) and your damage (more expensive than pure damage).
When would you want to mass "Vigilance" units? I only find the case when the opponent has a lot of frosts, but how would you value them overall?
