When Wan Shi long enters, target nonland permanent's owner puts it into their library second from the top or on the bottom.

Whenever one or more cards are put into a library from anywhere, create two 1/1 colorless Spirit creature tokens with "This token can't block or be blocked by non-Spirit creatures."
