Poisonous



Poisonous is a minion ability that causes any minion damaged by them to be destroyed. Poisonous minions on the battlefield are marked by a bubbling vial of poison at the bottom of their portraits. Poisonous is a type of triggered destroy effect.

Prior to Patch 7.1.0.17720, the Poisonous ability was represented by the text "Destroy any minion damaged by this minion".

Poisonous is strongly associated to the Rogue and Hunter classes.

Strategy
While the stats of Poisonous minions are not always especially powerful, they offer a unique tactical advantage. Poisonous minions can destroy any opponent in a single strike, and can be used to single-handedly dispose of giants such as Ysera or Deathwing.

Poisonous minions are generally disposable, intended for a single swift strike. However, abilities such as Divine Shield can allow you to make more extended use of them.

Poisonous minions only destroy minions to whom they have caused damage. Minions shielded with Divine Shield will not actually take damage, and will not therefore be destroyed. Reducing a Poisonous minion's Attack to 0 through means such as Shrinkmeister will likewise prevent the Poisonous effect from occurring.

Opponents will generally want to destroy Poisonous minions as quickly as possible, especially if they already have a powerful minion on the battlefield. The presence of a Poisonous minion, especially a Stealthed one, is a great deterrent to summoning any valuable minions, since they will likely be immediately removed from play by the Poisonous minion.

Keyword
Poisonous is actually a triggered effect, but does not display the lightning-bolt icon found on all other triggered effects. However, when the Poisonous minion deals damage, the lightning bolt icon is revealed.

Before Patch 7.1, 'Poisonous' was not a keyword, but was represented by the text "Destroy any minion damaged by this minion", as well as a unique animated icon depicting a green bubbling flask. The case of the Poisonous ability was cited in 2014 by Ben Brode as an example where the developers could have added a keyword, but chose instead to simply describe the ability in full, since it was only found on 4 cards. This was changed in Patch 7.1.0.17720 during the lead up to Journey to Un'Goro, with the addition of the Poisonous keyword. The change was purely cosmetic, but appears to have been due to the introduction of a number of new Poisonous cards with Un'Goro, therefore justifying the creation of a keyword for the long-standing effect.

Poison vs Venom
At the time of its introduction, the keyword itself, Poisonous, was arguably technically incorrect for all four of the playable cards involved. This is because 'poisonous' animals such as snakes and spiders are in fact venomous, rather than poisonous; venom is injected whereas poison must be absorbed or ingested. For example, a venomous spider injects its prey with venom, while a poisonous frog is dangerous if eaten.

However, Ben Brode explains that the term "Poison" is inherited from World of Warcraft, where the term has long been for a range of abilities and items used to deal additional effects when applied to their weapons. Hearthstone itself already contained a few such cards at the time, with more planned for the then-upcoming Journey to Un'Goro.
