Discard effect

Discard effects are effects which cause the player to discard cards from their hand. Discarded cards are removed from the game, without activating Deathrattles. Discard effects are most commonly found on warlock cards.

Discard effects are distinguished from overdraw, and remove from deck effects, both of which remove cards directly from the deck without entering the hand; and from Tracking's "discard" effect, which in fact removes cards directly from a special display zone without entering the hand. While similar to discard effects, neither is considered a discard for game purposes, and will not activate related effects.

Notes

• Cards which are discarded through discard effects are revealed to the opponent, which can present a strategic disadvantage.

• All discard effects discard cards randomly from the player's hand. As such, almost all discard effects add a substantial element of RNG and risk to the game. Deathwing and Cataclysm are the exception, with results entirely (and woefully) predictable.

• Discarded minions are not considered to have died, and therefore cannot be summoned by Resurrect.

• Effects that trigger from discards trigger only when discarded from the hand, not from the deck or when overdrawn.

• Technically, "discarding" a card refers to removing it from play while it is in the hand; for example, only cards discarded from the hand will activate related effects. Removing a card from play while it is in the Play Zone (the battlefield or weapon slot) results in it being destroyed, while removing it from play while it is in the deck requires overdraw or a remove from deck effect. Tracking's "discard" effect removes cards from play while in the Set Aside Zone (the zone used for Discover effects), and thus is not considered a discard.

Strategy

The negative repercussions of a discard effect can be removed entirely by not playing that card until your hand is otherwise empty. If this is not possible, they can be minimised by making sure your hand contains only cards you are willing to lose, such as by making sure to first play your most valuable cards.

Discard effects are mostly found on warlock cards, serving as an additional cost to playing a card at an otherwise unusually low price. This may allow the warlock to put out powerful minions at an early stage of the game, or deal strong damage on demand. While the card loss is undesirable, warlocks are able to easily compensate for this using Life Tap, especially in later rounds when mana is more plentiful. While the total cost of playing such a card is therefore in fact unusually high, the ability to delay paying that price until a later round can offer a strategic advantage.

The order in which discard effects are activated is of great importance. A warlock whose hand comprises two Doomguards and a Soulfire has two ways of playing their hand. Playing a Doomguard first will guarantee both other cards will be discarded, while playing the Soulfire first will guarantee that one Doomguard is retained. In most cases the player's hand will contain a variety of cards, making it impossible to entirely predict the outcome. However, the player can still control events to some degree by choosing which cards to play before the discard effect, ensuring that those cards will not be discarded.

When it is not possible to empty the hand of all important cards before playing a discard effect, warlocks can also choose to use Life Tap to add more cards to the hand, reducing the likelihood of a specific card from being discarded. For example, a warlock with a Soulfire and a Loatheb in their hand may use Life Tap to draw an Abusive Sergeant, in the hopes that playing the Soulfire will discard the latter card instead of the Loatheb. However, if an even more valuable card is instead drawn, the warlock may regret having used Life Tap before playing Soul Fire.

Starting with The Grand Tournament, warlock cards with discard synergy effects have been added, which aid in mitigating or removing the disadvantages of discarding cards. Fist of Jaraxxus and Silverware Golem are played when discarded and have more value if doing so, while Malchezaar's Imp and Clutchmother Zavas make the warlock's hand more powerful as cards are discarded. Discard effects are the focus of the Warlock quest, Lakkari Sacrifice.
