Looking through my logs it looks like 2006 would have been my last strong neutral conjurer, so sometime after that probably. My time frame in CF I always find is a little odd as I realize things I think are new are ten years old... I can't necessarily say what happened, but archons and angels are both definitely much harder to keep than they used to be as a neutral conjurer to the point it's not fun really. Anyhow, maybe something to think about in the future someday for other players who would like to play them. Thanks.
