The Spike Brothers are a champion bloodball team, a sport which is a combination of rugby and american football. Their focus in battle is replacing rear guards to gain more attacks as well as gaining more power by putting cards from the hand into the soul. But this clan has a massive focus on offence, making Spike Brothers a rush-down clan if anything.
