When Wan Shi Tong 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."
Wan Shi Tong, All-Knowing's last ability triggers only when cards are put into a library from somewhere other than the library. It won't trigger when you scry, surveil, or otherwise reorder cards in your library.
