This is Grell's most dangerous experiment yet, so he's relying on the wisdom of the ancient Byzantine engineers.
Yes. Yes it is. In Saviors of Kamigawa, this card would've been IN-SANE. Draw 20 cards, go down to 1, your Maro swings for 20+. Win. Or whatever. Geez. That's ridiculous. Or the words enchantments if you had enough mana. Or something that does something when you draw a card, like gain you life. This card isn't terrible. Totally worth it if you can restore your life and keep the cards.-Nameless one
Of course it's not terrible. Any card with the phrase "draw twenty cards" would have to try very hard to be bad.
Combo decks ahoy!Huge effect + Huge Drawback is hard to make because there are always ways to break the symmetry. The lesson of Donate+Delusions or Phyrexian Dreadnought + Pandemonium weighs heavy upon those of us who like these sorts of cards.
Empty your mind.
