Choose your skill set wisely. Choose your skills based on your current strategy as well as the response from your opponent's card. Examine the secondary effects of a move, and not just how much damage it does. To get more skill points, grind previously completed levels to earn experience points and level up. Each time you level up, you will gain Skill Points that are assigned to learn new Skills or upgrade existing ones. Consider learning four skills with your Curios to always have an option besides the usual attacks, then upgrade the ones that are best suited and cause the more damage. Each Curio has different skills; determine which of them are the best and upgrade them. Do not forget about the basic skills that do not require mana; they are very useful in situations where you are out of mana.
