Tui, The Moon Spirit

Lifelink
When Tui, The Moon Spirit comes into play,
you may search your library for La, The Ocean Spirit and put it into play then shuffle.
When Tui attacks with La, it gets +2/+1 until
end of turn.
At the beginning of your upkeep, if Tui is in
your graveyard while La remains in play, you
may return Tui to play.
