Silence is zero mana so it's similar to a turn 2 yeti. I understand innervate is more versatile, but priests can heal and you know how annoying it can be when a priest can keep a blademaster alive.
I would still consider taking circle of healing and taunters like argus/sunfury so it doesn't become a dead card.
I don't have the cards to try this out. Not sure if anyone has already tried this or want to give it a shot.
