Maybe it's an idea for the developers to look into changing the odds that a card gives you a magic attribute.
I don't have a clue what the actual numbers are on this but it seems like the odds you get a magic attribute is way too big if you compare it too how many heroes are being used that actually could benefit from this.

So in my humble opinion it would be nice if the developers team would keep that in mind and check out the percentages. People seem to use less magic heroes, so that actually makes the chance you get a useful sanctify smaller I think.
I could very well be wrong tho..

I totally do not mind the game of chance tho it must suck if you only have bad luck. Getting the wrong attribute ah well.. i can live with that. The fact they are unsuccesful so often is what bugs me more.
