Hyacinth, Shifting Eden

Flying, Vigilance
When Hyacinth enters the battlefield, you may
have up to three target lands you control become
3/3 elemental creatures. They're still lands.
If a land you control would leave the battlefield,
instead return it to your hand.
{w}{u}{g}: Exile Hyacinth, return it to the battlefield
at the beginning of the next end step.
