Crackling Doom

Crackling Doom is a shaman spell card, from the Arena unique set.

How to get
Crackling Doom is unique to the Arena and can only be obtained via drafting it during an Arena game.

Crackling Doom is uncraftable and cannot be crafted or be obtained from card packs.

Strategy
Crackling Doom is an extremely effective board clear, able to wipe out almost any minion played by an opponent at any point. Since even the most healthy minions like Malygos and Ysera have 12 health, this card is able to easily remove them from the board. Unlike most other board clears, which cost a high amount of Mana or have other drawbacks, the fact that this costs 0 Mana means the player can follow it up with minions on the very same turn to take back the board. Players can also make some use out of the absurdly high overload of the card. If a player plays Crackling Doom on turn one, they can immediately follow with a Snowfury Giant, which will cost only one mana, giving that player an 8/8 body before the other player can respond. However, this is an extremely rare case, since it's unlikely that both cards will be drafted into the same deck, as well as being drawn by turn one.

Lore
The actual “Doom” of the card is said to have come from one of the ancient ones, furious with anger.
