Three credits for a 2 sub barrier that etr is decent enough value as is. But at 5 strength this card becomes very expensive very fast. The "only one sub can be broken" clause (like on Afshar) makes it incredibly annoying to deal with unless it is bypassed. Giving the corp money and an advancement counter is nothing to sneeze at, especially since this combos perfectly with Builder of Nations. SSO will also love this card, since they can immediately bring it up to triple advanced with their ability.
Very solid card, one to watch out for.
