Rycroft, Lord of Celtanis

Whenever you cast a noncreature spell, you may
draw a card.
Whenever you draw a card, you may draw an
additional card and then put a card from your
hand on top of your library.
{2}{u}{b}{t}: If you have drawn 7 cards this turn,
you may play the top card of your library
without paying its manacost.
