I think she is the superior 5 mana lifegain angel. Much like CML implies in the article, Baneslayer Angel basically comes off as a bad joke. Simply pushing a beater by giving it 3 keywords on top of a solid body is boring, particularly on a high end card and PARTICULARLY in white that already gets strong high end cards. Archangel of Thune can do just as much work as Baneslayer Angel, but does so while supporting themes and requiring you to do a little work to get it. She has an automatic slot in my cube.
