April 2016 Card Nerf
It was announced on April 20th, 2016 that Blade Flurry would receive a nerf.
- Mana cost increase to 4, up from 2.
- Now only deals damage to enemy minions - does not include the Hero.
Quote from BlizzardBlade Flurry is a problem because it enables both board clear and heavy burst damage, and it’s also an obstacle to adding better cards for Rogues. To address these issues, the cost of Blade Flurry is moving from 2 to 4 mana, and it will now only affect minions, so that Rogues have to choose between removing threats or damaging the enemy Hero.
