Getting rare and better cards
Upgrade your deck to Super Rare+ and higher. You can increase the chance of getting a Super Rare and better card by using a higher ranked deck in exhibition games. Increase the meter in the upper left corner that displays the combined power of your cards by training your cards. Those trained cards will also have a better chance of winning matches and give you more card picks in Exhibition mode. Repeatedly play Exhibition mode games, against opponents that have low total game plays and the most losses. Win King of the Ring championships. This is time consuming, as there are fifty games that must to be played and the cards will lose their value. Charge and replenish energy to keep your wrestlers in top shape. Save boosts for the later games, when they will be needed more.
