So for decks that play minions with overstatted health, and the typical combo priest but with an additional activator? Combo priest definitely did not need this, they had enough with shadow vision and crazed alchemist, so I'm curious what kind of deck this card would be played in.
That's what I thought. It's turn 6 and only onwards will the minions get the effect. Then you need to draw them, play them and attack / have taunt to be of value. Way too slow in an aggro meta, but might thrive in a control enviroment.
