Mirrodin Besieged (MH1-57) is a rare blue enchantment. As it enters you choose Mirran or Phyrexian, with Mirran creating 1/1 Myr tokens whenever you cast an artifact and Phyrexian drawing then discarding at each end step with a potential alternate loss condition if fifteen or more artifact cards are in graveyards. It supports artifact-focused strategies by generating creature tokens, providing recurring card selection, or serving as a long-game alternate win condition.
