If possible, start hero powering on turn 1. Your next objective is finding a coin. Turn 2 you want to buy a minion and hero power, turn 3 you want to level, buy a coin and hero power. This allows you to go to tavern 3 on turn 4 and coin out the last hero power, giving you a lot of tempo. Without the coin, sell your minion and usually still correct to go 3 on 4 because of how much power it gives you. Continue hero powering every turn afterwards and on 8 you'll have the next golden+discovery. First set of hero powers is for tempo/power and the second one to give you a direction for the game

With Eudora you wanna start Heropowering starting Turn 1. Stay down on Tavern 1 Tier for an extra turn to then level 2 times in a row to trigger your first Treasure on Turn 4 and Tavern 3 to discover an early 4 drop. After that you should also invest into generating a 2nd treasure to potentially discover a 6 drop on turn 8 with it. Going for a 3rd Dig is barely ever worth it
