Tactical Objective cards have been hard to get ahold of for retailers, either because there is simply not enough of them or they were popular. Regardless, I have now heard a date as to when these cards will become available again, and we are still a few weeks out. So a little patience if you are still waiting for some.
Please regard this as as rumor, as we have had no official announcement on this.
