At the beginning of your upkeep, you may gain control of target permanent until end of turn. If you do, untap it and it gains haste until end of turn.

8/1/2008: If you already control the targeted permanent when the ability resolves, you still need to choose whether or not to apply the effect. If you choose to apply it, the permanent untaps and gains haste. If you don't, it doesn't.
