You can use one card per run, which may help extending your distance and score. The Revive card is very useful, as it gives you another chance of running without losing your progress (score), together with Health Boosts that can increase your survival. Do not always use your best character. Alternate between cards and level each one up evenly to get a better chance of evolving from the start. Once a card is at level 5, retire it and work on the next card. Fusing two maxed cards will allow your character to evolve. You can use Evolution to evolve a card with another card in the same level. The basic card pack only costs 1,000 coins. It contains a variety of boosters and either a Batman or The Flash card. You will need those cards to level up and fuse cards together. When you have enough coins, you may want to consider purchasing the pack.
