Zebra Grass with Moon

As an additional cost to cast this spell, sacrifice a Cardian artifact.
When Zebra Grass with Moon enters the battlefield,
reveal the top card of your library and put
that card into your hand, then you may cast it
without paying its mana cost if it is a Cardian
artifact creature. Otherwise, put it into the
graveyard. When a creature battle with Zebra
Grass with Moon this turn dies, you may draw
a card.
