This + Wistful Thinking/Time Spiral = uber win. Geth's Grimoire is a sick card combined with the right discard spells. Time Spiral makes each player discard their hand and draw a new hand, while untapping 6 of your lands! - and with the Grimoire on the battlefield, you can draw extra cards equal to the amount of cards your opponents discarded! Wistful Thinking is another card that gets really awesome with Geth's Grimoire. You pay 3 mana to make your opponent discard 4 cards and you draw 4 cards! Combine with Underworld Dreams and Megrim for extra craziness!

Great one, if used in combos.. cast mind rot and draw 2 cards for each grimoire in play (i usually get 4)... use witch Honden of Nights Reach to get draw in upkeep everyturn.. in Magic there is a lot ways to make discard, and more cards for you and less for opponent is always good hing. But also, there are lots of artifact destroyers and counters in Magic..
