How does this win?

This is a combo deck called Eggs. You draw your whole library using the artifacts, sacing them to Krark-Clan Ironworks and replaying them with Faith's Reward . You eventually win by using Pyrite Spellbomb over and over with Faith's Reward and Conjurer's Bauble .

Ah. Okay. Thanks!

I love this archetype. Have you considered the version with more opens and emrakuls for the win?

What do open and emrakul have to do with each other? Emrakul would wreck this deck since I would die to the draw step if I ever played it after comboing out, and it would really suck to have it hit my yard.

The main reason I prefer the emrakul plan, is that it basically turns the deck into a three card uncounterable combo, which isn't too hard to assemble with all the draw. That way you don't have to go all the way off. Also, if you only use opens, you can afford to always crack your eggs immediately, and not have to wait for a Faith's Reward . I tested it like a dozenish times, and it seemed like a pretty strong variant. I actually got the idea from an article by Caled Durward on CFB. You might wanna check it out, as even if you don't really like the open/emrakul plan, there's still a bit of insight to be taken from another KCI deck.

By the time I have enough mana for Emrakul, I should be well into my deck and be comboing off. Also, there are decks that can deal with an emrakul, and it's not an insta-win. And Venser, Shaper Savant and Mindbreak Trap both stop it.

If you link the article, I will take a gander at it though.

I misremembered, it was a video, not an article. Here it is anyway.

+1 love combos :D
