Behavior Chart

When Behavior Chart enters the battlefield, if this is the first time an artifact named Behavior Chart has entered the battlefield, each player gets ten behavior counters.
Whenever a player causes another player to gain life, draw cards, or get permanents, that player gets a behavior counter.
Whenever a player causes another player to lose life, mill or discard cards, or lose permanents, that player loses a behavior counter.
A player with no behavior counters loses the game.
