I am testing this:

SB:

4x Leyline of the Void
4x Serum Powder
3x Helm of Obedience
4x Spoils of the Vault

t0 Leyline itself is already devastating to some decks. All we gotta do is get the Helm and accumulate 5 mana. Shouldnt be hard since after siding out combo cards all we got left is pretty much mana creators.
