When first starting, play Quick Games until you have a good set of Rare and Uncommon cards. However, do not train any of the cards yet. Focus on putting together the best possible starting lineup based on the cards you acquire. Continue playing against opponents with few or no matches to win easily. Once your deck is filled, choose the five best cards, giving priority to the ones that can be combined. Then, begin training your best cards.

Win or lose, you will still gain cards. However, you will get more cards by winning. To increase your chance of winning, look at the number of total games played by an opponent, and select those that are familiar with the game. If a player has more losses than the others, this also may be a good indicator of a weaker deck.
