I set up a mana base with greenseeker, expanse, and tusker, while discarding either the Tusker or something with Greenseeker. Also, their are 8 reanimation spells including 4 with flashback plus Teneb, im not sure where you got only 4. After that I built on the "losing creatures doesnt really matter" theme and put in the woebringer demons for a different kind of removal and the hulk to fetch a dragon if he dies.
It is slow...ive run into trouble against some goblin and kithkin decks that dont really get slown down against only 1 removal spell, but im not sure if interrupting the balance would be advisable. The only other removal spell i have considered is crime/punishment for semi-mass removal.
