• 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.
