Lau, Dreamer Of Dreams

Flying, vigilance
Whenever Lau, Dreamer Of Dreams attacks,
exile the top two cards of your library. You may
play those cards until the end of your next turn.
Whenever you cast your second spell each turn,
create a 2/2 blue fish token with flying and "non-creature spells you cast cost {1} less to cast" and
"{t}: Draw a card"
