A fast grinding deck. By enhancing the Ally count with Changelings, I am able to grind more cards in less time. There is little in here left for a fight, and that could prove to be the great danger, but three copies of Echoing Truth will, I hope, do something. Two copies of Extirpate should enhance this, once a threat reaches the graveyard, and the two can be deadly in concert. Also, the three copies of Lobotomy help by removing undesirables before they reach the battlefield (or after being bounced back).
