Leyline of Mutation

· Duskmourn: House of Horror · Nonfoil

If Leyline of Mutation is in your opening hand, you may begin the game with it on the battlefield. You may pay {W}{U}{B}{R}{G} rather than pay the mana cost for spells that you cast.

Life thrives in the Hauntwoods, but it follows its own laws, unbound from the natural order.
