I'd love the ability to have the game automatically grab a number of man potions when you got to less than the cost of your most expensive spell (only enough to get you to number high enough to cast the most expensive). Even better, though, would be if the spell scrolls were always behind the coins and mana.
What's the point of the New Intel card? It gives a card, but it is a card itself, so there's no net gain. And it might give back its energy cost, but it might not.
