i do not like 3 Hero of Goma Fada, i played against you when you play this deck and the hero does not do much

Bloodbond Vampire in place of 1 Hero of Goma Fada

sorry ageist should be against

you want Silkwrap in sideboard

I like Serene Steward over Bloodbond Vampire myself.

Now the more I look at it. Why not just take out the 3 Expedition Envoy and put in Serene Steward? Also you could run only 1 Ally Encampment and put in two more Caves of Koilos, you taking pain isn't that big of a deal here if your deck is working right. And if it's not, then you prolly lose because this deck runs on synergy. Honestly mid-range and control are going to do a decent job of keeping you in check until they turn the corner, unless they can't and you explode on synergy. So I don't see the lose of life as relevant. Also main boarding some removal is a good idea. I would suggest Declaration in Stone, it's way too good right now.
