Rulings:

• 3/1/2010 You may target any two (or fewer) creatures. It’s okay if any of them are already tapped. If you cast Permafrost Trap for <img src="/Handlers/Image.ashx?size=small&amp;name=U&amp;type=symbol" alt="Blue" align="absbottom" />, you don’t have to target the green creature that entered the battlefield under an opponent’s control.
• 3/1/2010 If a targeted creature is untapped at the time its controller’s next untap step begins, the second part of the ability has no effect on it.
• 3/1/2010 If an affected creature changes controllers before its previous controller’s next untap step, this ability will prevent it from untapping during its new controller’s next untap step.
