Bladestorm is a common spell that deals damage to all enemy units and structures. The amount of damage done can be increased by leveling it up. Bladestorm can work in any kind of deck that needs area damage.
Bladestorm works as a good counter to aggro or swarm decks, as they have lots of units on the board at once.
Bladestorm can also deal with structures that are placed in a position you can't attack directly. You can use Bladestorm repeatedly or combine it with other damaging spells like Needle Blast to take care of full-strength structures.
The low damage output per target of Bladestorm makes it very effective if there are a lot of enemy units and structures, and very ineffective if there are little.
