A Maralen Hyper-Combo Deck.
Mostly just a prototype, still need to get the swamps for it and change a few things around with the last few sets.
I was about to suggest Imperial Seal for obvious reasons, but then I realized it costed more than the rest of the deck put together.
@ Orbrunner ya, I can afford an $800 card; but I can also afford one-hundred, $8 cards, which I think is superior. Or in this case, a few expensive moxen, and a lot of bulk. And I'm not even sure Imperial Seal is that good, Vampiric Tutor might be coming out; but I have to play the deck a few more times.
