can vedalken shackles take manland?

[Kenji]

This is actually addressed in the Gatherer rulings for Vedalken Shackles:

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.

So, obviously you can only take a manland after it has become a creature, but afterwards you'll keep control of it even when the land stops being a creature.
