Leth-Orvier, Incarnate

Flying, Haste
When Leth-Orvier enters the battlefield, exile
the top three cards of your library. Choose one,
you may play that card until the end of your next
turn, put the rest into your graveyard.
Leth-Orvier has power equal to the number of
lands on your battlefield plus the number of
lands in your graveyard.
