Nemesis featured 143 cards (55 commons, 44 uncommons and 44 rares). Nemesis's expansion symbol is the axe of Crovax, the main antagonist of the story’s Rath component. The set continued Mercadian Masques's themes of spellshapers, rebels and mercenaries, and cards with alternative casting costs. Nemesis is generally considered to be the most powerful set of the Masques block. A card of note is Ascendant Evincar. It was the first card to represent the same legendary permanent as a previous card following a major change in the character's storyline. The card was not named "Crovax, Ascendant Evincar", in order to avoid confusion over whether the "legend rule" came into effect when the Evincar and Crovax The Cursed were both in play. This policy was later dropped with the printing of Ertai, the Corrupted in Planeshift. The set featured Rootwater Thief, Mike Long's invitational card.
