Severin is Necessary for the World, Pyre

I was reaching for Roshi's worldpyre deck, but I lack 4 End of Story's, to go even with the golems, etc..
So I replaced golems with cull the deck, and use 4 Shen-Ra Speaks.
The individual kill spell count is good with eremot's designs, desert alchemist, slay, and necessary measures.

Necessary measures is the star card, with worldpyre of course. It can be used as a kill spell, but it also tutors for solitary units in your deck. Not a problem really, the games aren't so long you need more than 1 of many of these units.

You haven't lived until you've Necessitated Vara, with Azindel in the void, then worldpyred Vara into existence, pulled out azindel, and his two little guys, and pulled 3 more shadow units with them. There are 11 shadow units in the deck (if you include mauve)
From beyond turns into mauve sometime during the early/mid game, solitary, and she goes really well with gnash, who pops out an insect totem with killer at the beginning of your turns, drawing 2 per round.

Card draw is unbelievable, cull the decks, smuggler, plunders, necessary measures, gnash, azindels, mauve, and Vara, all contribute to card/unit draw and going wide. And usually it starts turn 5.
