The goal is simple. Play Call of the Ancients, use Whispering Wind to discard 1-drops and get ur sentinels in play.
The deck was much better when Copper Conduit and Inspire were unnerfed, but I have faith in the deck, with better 1-drops coming in future sets.
They can act as decent chump blockers and card draw and you have the bonus ability to negate 3 cost spells. I made room for them by getting rid of predator's instinct, seek power, cliffside porter, gloaming wisp (you REALLY don't want nightfall in a deck where every matchup is guaranteed to have higher average value per card).
How important would you say blind storyteller is to the deck cohesion?
Blind storyteller is fairly important to the deck. It helped me many times dig out the wind or the "call the ancients". Even one application if you get from it, it gets you that much closer to the combo.
Snow pelting and yeti do seem good. I had Copper Conduit and Inspire before, and I struggled to replace them as they were really key cards in the deck.
This deck can only get better with time, as there's very little set 2 and 3 cards, the base is set 1 which I don't think will ever rotate.
