Phase one: corner kicks. Both teams send five players to each end zone. Goalies stay put. First player of one team picks a corner, does the corner kick, play continues for ten seconds. Once time runs out, at the other end of the field, first player of other team picks a corner, does the corner kick, play continues for ten seconds. Repeat for second through fifth players of each team. After all ten corner kicks, if tie is broken, game over. Otherwise, the goalies (and no one else) switch ends. Repeat corner kicks for the next set of players. After everyone (except goalies) has taken corner kicks, either tie is broken, or move on to second phase.
Phase two: free kicks. Keep the same five-five-goalie split of each team. First player of one team picks any spot on the field out side the box, free kicks from that spot, play continues for ten seconds. Once time runs out, do same thing at other end of the field. After five free kicks from each team, either tie is broken or goalies only swap ends, and play continues with next set of free kicks. After everyone has take a free kick, either tie is broken, or move on to third phase.
Phase three: penalty kicks. Same as current tie breaker.
The idea behind this set of tie-breakers is that play changes from most like regular play to least like.
