Llyrian, Einic Caretaker

When Llyrian Einic Caretaker enters the battlefield, look at the top five cards of your
library. You may reveal all island cards and put
them into your hand. Put the rest on the bottom
of your library in any order.
You may play an additional land on each of your
turns if the first land you played that turn was an island.
There is much to care for in the Ein.
