Based on the combination of the Crown, Scepter and Throne. Tezzeret makes this combo very consistant. An other win option is Inkmoth Nexus and the last one is Wurmcoil. So far I got good results. I have spreading seas in the sideboard for Valakut and mono black control. Spellskite is mostly here for Splinter Twin. The Zenith is for the aggro decks. What do you think ?
