The combo with Grinning Ignus does not work. All your effects lower casting costs by colorless mana. At best, you can cast the Ignus for one red. The, the Ignus's ability also costs one red, and only adds one red to your pool. That combo requires 2 red mana, but only produces one. The combo will die out when you run out of other sources of red mana.

Use Chancellor of the Dross to have a turn two win with Rite of Consumption. You have more life to pay and need to pay less of it.
I made the change.
I guess that does also work. Thanks.
I think you should put in Crucible of Worlds, elixer of immortality, and possibly Mirror-Mad Phantasm. I like the fact that if you activate Goblin Charbelcher after Mana Severance to get rid off all your lands, it baisicly lets you stack your deck.
I didn't think about that. You can also use 200 Emrakuls instead of the hands of emrakul (to aviod using the leyline), but noone really has 200 Emrakuls so I tried to find a way around it. I gusess you do need the 200 Emrakuls (or other legend eldrazies).
