Pact Weapon

As long as this Equipment is attached to a creature, you don't lose the game for having 0 or less life.
Whenever equipped creature attacks, draw a card and reveal it. The creature gets +X/+X until end of turn and you lose X life, where X is that card's mana value.
Equip—Discard a card.

Mientras el Arma de pacto esté anexada a una criatura, no pierdes el juego por tener 0 o menos vidas.
Siempre que la criatura equipada ataque, roba una carta y muéstrala. La criatura obtiene +X/+X hasta el final del turno y pierdes X vidas, donde X es el valor de maná de esa carta.
Equipar—Descartar una carta.
