I'm really curious to see where the expansion takes AST. I agree with the others, I think an ability like the one you suggested would be too powerful. As it is I consume most non-Balance or Bole cards for Royal Road because in the end whenever I can increase damage dealt and decrease damage taken, the rest kind of deals with itself.

I think AST is in a really really good place right now and doesn't need much else done to it. What I actually would much prefer is for WHM and SCH to get the proc for a guaranteed crit of Cure 2 or Adloquium because I find that incredibly useful on my AST. When it happens at an opportune time that is!
