Cataclysm is an epic warlock spell card, from the Kobolds and Catacombs set.

Golden Cataclysm 1600 400


  • Deathrattle effects of minions destroyed by Cataclysm trigger after the hand is discarded. Playing Cataclysm with a Voidcaller in play and a demon in hand will result in the demon being discarded, not summoned from Voidcaller's deathrattle.
  • However, Voidcaller's Deathrattle can summon a demon from hand after casting Cataclysm if the demon is drawn after the hand was discarded, for example by having a Malchezaar's Imp in play when casting Cataclysm.


While this card is extremely cheap for a board clear, discarding your entire hand means in most cases you won't have anything to follow up with, unlike Deathwing which leaves you with a 12/12 and turns the board in your favor. Using this card means you will need to top-deck something worthwhile right afterwards, although this is made easier by Life Tap. Having or playing with a Deathrattle minion like Loot Hoarder can make up for these losses.

On the other hand, if you have Malchezaar's Imp, it'll negate this downside by redrawing your hand.

On the plus side, this card is a very strong enabler for Discardlock decks. Discarding your entire hand means you are guaranteed to summon a Silverware Golem or buff Clutchmother Zavas, and most importantly, it can be used complete the Lakkari Sacrifice quest extremely quickly and lets you play Nether Portal on curve.

This card can also be used as a finisher with Mecha'thun, allowing you to win the game with Mecha'thun, even before you have no cards in your hand or other minions.


Cataclysm was originally a passive ability for Destruction warlocks that increased the Fire damage dealt by all of their abilities. It was removed in the Mists of Pandaria expansion, but in Warlords of Draenor it made a return as an active talent which, after a 2.5 second delay, conjures a cataclysm at a target location, dealing heavy Shadowflame damage to all nearby enemies and afflicting them with Immolate.

The spell appears to have thematical ties to Deathwing, who in the World of Warcraft expansion of the same name caused a worldwide disaster known as the Cataclysm, which caused great destruction across much of Azeroth.


  • Probably due to his involvement with the Cataclysm, when the player's hero is Deathwing, he will say "Azeroth will break!" when casting this card (Although Deathwing is a Warrior, meaning that you'd have to find a way to obtain a copy of Cataclysm to trigger this interaction).
