Freezing Trap is excellent when all minions (well, most) cost at least 7, Dart Trap is great when most early hero power taps will be on an empty board, Flare is great when your Mage opponents are hoping to Mirror Entity and Effigy and Duplicate and so on.
Animal Companion (usually) makes a great early minion, and Eaglehorn Bow is great when nobody’s going to get in the way.
