Gatherer Card Rulings [Nov 2009]

• 12/1/2004: The creature's power and the number of Islands you control matter only when the ability is activated and resolved. After that, only the fact that Vedalken Shackles remains tapped matters.  You maintain control even if it stops being a creature.
• 12/1/2004: If Vedalken Shackles becomes untapped before its ability resolves, you don't gain control of the creature, even for a second.
• 12/1/2004: If Vedalken Shackles leaves the battlefield, it's no longer tapped, so you lose control of the creature.
