This Card i like Mana burn, only with bricks instead of gems.
It's different to storm of bricks or implosion, since storm of bricks uses your bricks to deal damage and implosion doesn't reduce the enemy bricks to 0 and deals Damage based on enemy bricks and quarry.
But in my opinnion, this card is far too strong, since it is a difference to consume all enemy bricks instead of gems. Bricks are used to improve the defense and without this bricks, the enemy is almost defeated after a strong attack with this Card.
