Trampa de letargo

Text:

Si tres o más criaturas están atacando, puedes pagar en lugar de pagar el coste de maná de la Trampa de letargo.
Las criaturas atacantes obtienen -3/-0 hasta el final del turno.

Rulings:

• 10/1/2009 You may ignore a Trap’s alternative cost condition and simply cast it for its normal mana cost. This is true even if its alternative cost condition has been met.
• 10/1/2009 Casting a Trap by paying its alternative cost doesn’t change its mana cost or converted mana cost. The only difference is the cost you actually pay.
• 10/1/2009 Effects that increase or reduce the cost to cast a Trap will apply to whichever cost you chose to pay.
