This is largely a creature-control concept, with the Odious Trow/Gift of the Deity combination a dangerous one. Wanderlust and Soul Bleed make it painful to keep creatures. Royal Assassin trims the corners and deals with those attempting to avoid deathtouch. Vampire Hexmagi are there to defend with first strike, and Urborg is there to make defenders have less of a chance of taking out my attackers with their first strike. There is a lot happening at the low end of the curve, as I wanted to use Jeweled Amulets to power my way to the 3- and 5-spots. The (4)/8/9/0/4 curve averages only 2.26 but take out the mana assists at the 0-spot and it quickly becomes evident why they are necessary, since the average climbs over 2.50.
