In my welcoming post I explained why. I want this program to be comprehensive and have the option of providing every level of advice players would want. The top players are not willing to give out their advice for free because they have to invest so much money into the game in terms of testing decks, traveling everywhere, etc., which is why if you want their advice, there has to be a subscription. Ads will never pull in enough money to cover those costs (they barely cover the server costs as it is - I usually have to pay out of pocket myself). :x
