good assessment. The only thing I'd have included is something about Mindsparker, nobody seems to be talking about that guy, and he's one of the more efficient bodies red's gotten in a while.
I think he might play like countryside crusher without just shutting off your land draws
Is it? It's a strange card because the two halves are pretty bad in situations where the other half is good. The anthem is unlikely to kick in during the aggro mirror (where lifegain actually helps), and the lifegain is unlikely to matter in against control (where the anthem does help).
Other issue is that it might not be an anthem straight away, especially with fetches and shocks and such. I don't know if the impact is sufficiently high to warrant inclusion in a deck over some other threat (Blade Splicer, Silverblade, etc.). But I also don't really support tokens and maybe am completely mis-evaluating.
I really liked the article. The evaluations on the Hydra and Lifebane Zombie were about what I expected but very elegantly put and well presented. Don't think you needed to waste time on Witchstalker, though, especially since there was not much to talk about. Also thoroughly enjoyed your analysis on Elvish Mystic
