What is infect?

Infect Mythic Rare

Creatures with infect deal damage to players and creatures in different ways than other creatures.

This creature deals damage to creatures in the form of -1/-1 counters and to players in the form of poison counters.

You've probably heard of +1/+1 counters. Creatures like Feral Hydra can put +1/+1 counters on themselves. An creature with Infect deals damage to creatures in -1/-1 counters instead of just dealing normal damage. Suppose an 2/2 Creature with Infect like Contagious Nim attacks. If the other player blocks with a 3/3, then instead of nothing happening when Contagious Nim deals its damage, it puts two -1/-1 counters on the 3/3 creature instead of dealing 2 damage. Now, the 3/3 creature is only a 1/1 creature. From then on, the creature weaker permanently unless they get +1/+1 counters again, negating its effects. Another part of Infect is that it deals poison counters to players. Normally, if a 2/2 creature attacks, and the opposing player lets the damage go through, that player would simply lose 2 life. But with infect, the player would get 2 poison counters instead. Here's the important thing: a player with 10 or more Poison counters loses the game.

There's only one way to get rid of poison counters: Leeches.
