Poisonous

(Redirected from Poison)

Poisonous is a keyword ability that uses poison counters. It was introduced in Future Sight, though the concept of poison counters is as old as Alpha.

From the Comprehensive Rules

502.69. Poisonous
- 502.69a Poisonous is a triggered ability. "Poisonous N" means "Whenever this creature deals combat damage to a player, that player gets N poison counters." (For information about poison counters, see rule 102.3d.)
- 502.69b If a creature has multiple instances of poisonous, each triggers separately.
- 102.3d If a player has ten or more poison counters, he or she loses the game the next time a player would receive priority. (This is a state-based effect. See rule 420.)

[edit] Rulings

If all damage that a poisonous creature would deal to a player is prevented, the poisonous ability won't trigger.
The player will get the stated number of poison counters each time the poisonous creature deals combat damage to him or her, regardless of how much damage that creature dealt.
If a player has ten poison counters, that player loses the game.
Although several older cards give players poison counters, none of those cards have abilities that trigger on combat damage.
