How Does Infect Work?

So what does that mean, exactly? When a creature with infect deals damage to a player, the player doesn’t lose any life as a result of the damage—he or she gets that many poison counters instead. If a player ever has ten or more poison counters, that player loses the game.Jan 10, 2011

How do infect counters work?

“Infect” is an ability. It means that it deals damage in the form of poison counters to players and in the form of -1/-1 counters to creatures. If a 2/2 creature with Infect deals damage to another creature, that creature gets two -1/-1 counters.
