Watcher of Cherry Blossoms

When this creature enters, sight X, where X is the number of Forests you control. (Look at the bottom
X cards of your library, then put any number of them on the top and the rest on bottom in any order.)

When this creature dies, clash with an opponent.
If you win, return this card to its owner's hand.
(Each clashing player reveals the top card of their library, then puts that card on the top or bottom. A player wins if their card had a higher mana value.)
