I switched Kaleb's Favor to Signal Flare, because I've tested it out to great success. It can still go face and is cheaper and more versatile than Kaleb's Favor. While Kaleb's Favor does pull power out of the deck, we can't be sure it would be the next power in the deck. The scout on Signal Flare allows us to directly scout power to the bottom of the deck.
If you don't have Into Shadow, use Kaleb's Favour instead.
