Thanks for the kind words!
The archons are all interesting and quite a bit stronger than the rares from Rebellion. I think Razi is the best of the bunch but Fithe, Bella, and Gorgug are right there too. I don't like Kaylia as much because I don't think the elf synergy is as good as ulunds or dwarfs for example and gorgug giving venka enrage is by itself insanely strong.
Kavor as I mentioned in my article is the only dragon little league summoner in modern and I think we'll see more Drakoshans in the future. Sheng Xiao, due to the nature of poison burst, can be a little random at times. If you get good poison bursts on the right targets he can be devastating, other times it can feel a little lack luster.
