The strat involves staying on tavern 2 and buying every Fire Baller and Snow baller you see. You should also buy your first 5-8 Strike Oils that you see, and every refresh spell. Specific heroes that give economy are much much better at this strat than your average hero. Chromie can buy all the tier 2 spells which gives you lots of free economy, Nobundo can copy a Strike Oil every turn, Cenarius can press hero power every turn, Kurtrus can get a free baller every turn, and Sire can get Temporal Tampering which is an auto win with this strat. Without a great hero power, you must rely on a good Timewarped card, such as Snow Elemental or Skipper or else it is unplayable, and you should level to play normally.
