In Shadowmoor,the first set in a new block, even the all-new game mechanics are warped. Wither and Persist make -1/-1 counters matter, and can turn creature combat into a meat grinder where attrition or reanimation can determine the victor. The untap symbol also makes its debut, allowing you to spring new tricks on the unwary.

Hybrid mana costs are back, and appear on over one third of the cards in Shadowmoor. Mono-colored hybrid cards join Wither, Persist, the Untap Symbol, and Conspire as all-new mechanics unleashed in this dark world.

Morningtide, the second and last expansion of the Lorwyn block, gives us more tribal craziness! This time the 'classes' are added to the mix: Rogues, Shamans, Warriors, Soldiers and Wizards. It introduces the new keywords Prowl, Reinforce and Kinship.
