Can't block or must attack

A drawback on the card itself in combat: "this creature can't block", "can't attack unless ...", "attacks each combat if able" or "blocks each combat if able". A restriction on every creature (Bedlam) is role:combat-control, and one an Aura puts on another creature (Pacifism) is removal.
