Ferocity maight be the least impactful ruleset compared to to others. The ruleset merely grant Fury ability to all cards. Fury by itself is rarely used, since its only double the damage to target which possessed Taunt. Consider others similar ruleset, Heavy Hitters; players would have better control because they would deploying cards with Knock Out ability to utilize it. But with Ferocity, players will tend to avoid deploying card with Taunt ability, which means its extremely slim the chances knowing that opposing players avoid the cause of trigger.
