The first hero power I like to use on tavern 3 or 4 and try to get a coin generator. If the game is going well, use the other 2 hero powers on 5 and 6, if the game goes badly use one or even both hero powers for tempo. Can also use hero power on turn 2 in some situations where you’d rather build early board presence and level afterwards. An alternative strategy is to hero power on turn 2 hoping you get a super big unit that can carry your early game and then level fast to 4/5 and hero power there before going to 6 for your last hero power.
