This is another way to identify a card, and can also clue you in to some special, often valuable cards: [7] Secret rares have a collector number higher than the total # of cards (supposedly) printed in that set, for instance "65/64" or "110/105." Secret rares can range anywhere from a couple of dollars to hundreds of dollars

Still, its one of the better and more flexible 4-drops you can play in decks filled with noncreature spells, and you can use it to manipulate combat in your favor and gain some life
