­Lifeleech Roach + Jace's Erasure

Oh goody, they erased Jace, now we can go back to life before OP planeswalkers.

Aaanyway. We've got... a giant black spider that taps to drain for one; and an enchantment that tacks a mill onto every card you draw.

Let's go with the drain enchantment, rather than the tap to mill creature.

That's a crazy price for that, btw. Retreat to Hagra gives you drain-one-per-turn on landfall, for more mana, and landfall is less reliable and less frequent than card draw.

­Subversion gives an upper bound on the cost, as that scales more evilly in multiplayer games, but I think this would cost 3 if not 4. See also Drana's Emissary which has the "upside" of being a creature, but that also makes it far more answerable.

Or, you know, compare this card to Underworld Dreams, which still sees a lot of activity. I really like Jace is Evil, and want to believe it costs 2. But realistically, it probably costs at minimum. Especially since this is a really good way to kill an opponent in a blue/black deck that does nothing but draw cards...
