My argument on the exert thing is that the opponent basically has no reason not to block this with their 3/3, because they'll either trade or they take 3 and keep their creature but Freya dies either way, and not killing their 3/3 in the trade is actually probably worse. In cost analysis, this is effectively a legendary Watchwolf, so the exert isn't really going to be necessary.
Reason is because they don't always have a 3/3 on their side of the board. You can easily play a heiarch turn 1 and play this and something else and then next turn swing with a 3/4 with this ability. This can be done before the opponent gets to establish a board. And it also makes chump blockers very weak against it. No chumps allowed. It's really good but not too good as is.
