Pretty bad, if it isn't discarded it's 4 mana deal 4 damage which is kind of bad considering soulfire, darkbomb, implosion. To make use of the discard mechanic, you have to have a card that discards in your deck, and this card, and then you have to draw them both at the same time, and then you have to hope you discard this card and not something else.
