This is a serious departure for me. I have been loath to use cards with flashback, undying, unearth, and rebound in any great numbers, salting these keywords into decks where the colors of core themes just made individual titles advantageous. This time I set out to use JUST those keywords. Naturally, a little more variety would improve the deck, and in fact I did include more than a handful at a time. The only non-land cards in the deck without one of those four are the three copies of Slitherhead, which has its own graveyard effect. In short, every spell can be used twice. At an average 2.68 converted mana cost, the 10/9/13/2/4/2 is a little spendier than I like, but the spells seem to be worth the wait at each spot.
