Your hero takes no damage until the start of your next turn.
Similar ideas have been tossed around im sure. I just wanted to make this after being butt hurt from losing as a rogue a bunch of times. I feel like there's a lack of defensive abilitites and taunts in the rogue deck and this would allow you to attack into minions without taking damage. I feel that this is a much needed mechanic as I end up doing so much damage to myself with the rogues hero power as well as other weapons like perditions blade.
