How about Dark Horse deck? You could play 1-cost fast event card for free, such as Lucky!. You could play 2-cost asset with 1 resource from upkeep + Fool, or 3-cost asset with upkeep + Labranche + Fool. Similarly, you could play Will to Survive with upkeep + Fool + On Your Own, or 3-cost event, such as True Survivor, Waylay, with no cost.
One problem is that The Fool is 3-cost asset, which is hard to play Dark Horse deck in the middle of the game. Luckily, here is a solution; if you find Fool in your opening hand, you don't need to concern this. What you need to do is improving your drawing ability :) Of course, my drawing ability is too poor to find; my Fool always places among the bottom five cards.
