After noticing how few spells were being selected (often none) we decreased the cost of all Spells by 1, every game, regardless of what's on the board.
This has made for a much more enjoyable and diverse game.
Sure, it leads to some crazy combos, but scary combos are the bread and butter of most deck-building games.
P.S. A lot of times, we also play to an increased victory point total, often 20.
Are you talking about 4 player games?
