If a CAMO Marksman tool is stuck on the deck board, it is typically because the CAMO fastener is not fully driven into the joist. Don't try to pull and remove the tool because you may break it. Rather, remove the screw by reversing the drill and backing it out or continue to force the screw into the deck board. Driving the screw in the rest of the way is the recommended method. Once driven in, remove the tool and continue with your project.
