I just dont see it being worth the chance of starting with 0 pillars but not getting an auto mulligan because of it worth the 1 cost. I can see what you're saying about using all the aether and such, but worst case scenario you have to wait one extra turn to play it. Its really not a life or death card in any deck, so that really doesnt hurt you much, or at least not nearly as much as starting with 0 towers would
