While playing the Blood Sun node in Battle of Four Tribes, I cast Lay Claim on my opponents Wayward Swordtooth while neither of us had the City’s Blessing. A few turns later I cast another Lay Claim on another Wayward Swordtooth, reinforcing the one I took earlier, still with no Blessing on either side. Another couple turns later, I get the City’s Blessing, but the Swordtooth still can’t attack.
I have in other games Lay Claimed a Swordtooth, then gotten the Blessing and attacked, so the problem seems to be in the reinforce. My assumption is Swordtooth’s City’s Blessing ability gives it a “Can’t attack or block” status that it later also removes, but when I gained control of it as a reinforcement only the status got copied, now unattached from the ability that could later remove it.
