It looks nice! Why don't you play some SoD?
sod gives you just 16 hp, sancts are better. they also protect you from devour, sob, bh, discords
+ some Novas and Protect Artifacts
Youre pretty dependant on that your voids stay in play.
You dont want to type GG just because they drop SoF or Pulvy the first turn.
i know, a first turn pulvy is gg (as for many other decks). SOFO is not a problem, you can siphon it well, try adding +1 or +2 siphon -1 or -2 towers if you feel like you need that CC. protect artifact will only be really useful against pulvys, so i dont find it useful to change the deck to a nova one just for that. you can survive well a couple of steals and explosions
Swap a pair of pillars for pends. Do you have enough stall to survive a whole game without dieing?
yes, i have =)
