Doran, Besieged by Time

Each creature spell you cast with toughness greater than its power costs {1} less to cast.
Whenever a creature you control attacks or blocks, it gets +X/+X until end of turn, where X is the difference between its power and toughness.

Te cuesta {1} menos lanzar cada hechizo de criatura que lances con resistencia mayor que su fuerza.
Siempre que una criatura que controlas ataque o bloquee, obtiene +X/+X hasta el final del turno, donde X es la diferencia entre su fuerza y su resistencia.
