Can you chain it? If you kill a minon with the copy, will you get yet another one?

Am I missing something? This seems incredibly counter productive and bad.

I agree, but I still think there is a long way to the two others. When Descent was being revealed it seemed like competition to make the strongest HS card of all time to me. I don’t have that feeling with anything from this expansion, but it does seem solid.
What I absolutely love, though, is all those flavourful cards.

I think it seems lower. It’s normal for the power level to rise through the year and then lower at the start of next year again. So really it should be compared to the other December expansions. I don’t think this is anything at all compared to Descent of Dragons or Kobolds and Catacombs. I think it seems stronger than Rastakhan’s rumble, but that entire year was on the weaker side to turn down the heat a bit after Kobolds and Catacombs, I think.

I’ve actually had a good time playing against both pure paladin and guardian animals druid. Especially the druid one is a really intense matchup and difficult matchup.
(I’ve mostly played big warrior).

I think Aeon Reaver has another thing going for it – priest removals often favour low-attack minions, which this one obviously doesn’t. If you run a deck with many removals, this could help fill a missing space. That said, such a deck probably doesn’t care that much for the body that comes along.
