Does Liliana of the Dark Realms have good synergy with Pack Rat? Seems like you could fetch for a land each turn, and then toss it to Pack Rat, making a token, and growing them at the same time. is this just wishful thinking? I would assume that it would have to be either Mono Black or maybe Black/Blue Control or Black/Red Control? You are going to certainly need removal, but having card draw will also be important since you don't want to be top-decking. I think that Blue/Black would be the best route to accomplish this or possibly G/B since G/B seems to be pretty powerful thus far with what I've seen.
