Mark Rosewater is teasing us via twitter, check out these hints at an upcoming spell in Rise of the Eldrazi!

[easybox]Rise of Eldrazi has a blue spell that cost U and has the text: "Draw three cards." It's not a reprint.[/easybox]

[easybox]The cost as printed on the card is U. The sentence "Draw three cards." is a sentence in the rules text. Is there more text? Maybe.[/easybox]

[easybox]No, you don't have to discard any cards. When the spell resolves you are up three cards.[/easybox]

Seems tasty!
