cars of Mirrodin's Asceticism is a clear call-back to the original Mirrodin's Troll Ascetic, turning all your creatures into regenerating, holy-crap-is-that-better-than-shroud-having monsters (and implying, incidentally, that Troll Ascetic's unique properties are due at least as much to being an ascetic as to being a troll). But in addition to being a call-back, Asceticism was also a call-forward—to Mirrodin Besieged.
