Iname, Christmas Land (EDH / Commander)

The goal of this deck is to win on turn 1.

The combo goes as follows:

1) Play swamp
2) Play Jeweled Lotus
3) Play Dark Ritual using the swamp from step 1
4) Play Sol Ring using 1 of the 3 floating mana
5) Sacrifice Jeweled Lotus
6) Tap Sol Ring
7) Play Iname, Death Aspect (commander); its ability triggers and you put every spirit in your deck into your graveyard
8) Play Songs of the Damned
9) Finally, play either Exsanguinate or Torment of Hailfire with X being as large as you can afford with your enormous amount of mana
10) GG

If you don't get this turn 1 play, you can strive to achieve it throughout normal gameplay by collecting all the pieces required to set off the combo asap.
In the meantime, Knight of Dusk's Shadow can help prevent opponents gaining life while your deck puts up continuous spirit-tribal threats including plenty of recursion.

Secondly, the Vito, Thorn of the Dusk Rose + Exquisite Blood combo and Mortal Combat are included as the alternate win cons.

Finally, if neither of those are working and your opponent has a ton of life, Tainted Strike can be a final hope if you've managed to get an unblocked 10+ power creature attacking the opponent.
