Watcher of Cherry Blossoms

When Watcher of Cherry Blossoms enters the battlefield, sight X, where X is the number of Forests you control. (To sight X, look at the bottom X cards of your library, then put any number
of them on the top of your library and the rest on bottom in any order.)
When Watcher of Cherry Blossoms dies, clash with an opponent. If you win, return it to its owner's hand.
