While playing with leveled up cards is more interesting you can play with 1 level cards to make money without spending lots of money to level up your cards and also train for novice tournaments because in novice tournaments you can only play with level 1 cards. The good thing is that it's more easy to sell level 1 cards than selling combined cards. It means that whenever you don't want to play steemmonsters you can get rid of easily 😁. Also every day you can get a free reward card and right now their price went up a lot. Apart from daily quests every season end you can get free reward cards depending on your league.
