Rulings:

• 10/1/2008 You choose the target when the ability triggers. When the ability resolves, you choose a value for X and decide whether to pay <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" />. If you do decide to pay <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" />, it’s too late for any player to respond since the ability is already in the midst of resolving.
