You will capture Curio DNA randomly during battles. This gives you a chance to replicate and gain the Curio if you spend regular coins or always get it if you spend premium currency. Unlike the Discs that you can get in the Shop, you will know exactly what Curio you will get and pay less per Curio. However, if you spend regular coins you run the risk of not replicating the DNA successfully. Do not use the Curio DNA when you already have that Curio and do not need a new one.
Elemental properties
Each element has their own advantage and disadvantage from the others. To take advantage of this, check the wheel of element during a battle by tapping on the teal button at the top center of the screen. This will show which elements have an advantage against a certain element. Elements that are not next to each are neutral with each another.
Evolution
Only evolve higher tier cards. You must spend currency and sacrifice unwanted cards to boost your primary cards.
Getting rare Curios
It is difficult to obtain rare Curios without the use of premium currency. Save as many coins as possible by replaying previously complete stages repeatedly. After accumulating a few hundred coins, go to the stages where two stars and better monsters are encountered. You then have to rely on luck to get a rare Curio. Earn gems by referring friends. For your first referral, you will be awarded a two star Curio and 50 gems. Keep referring friends, and once you reach fifteen you will get 200 gems. Once you have 300 gems you can purchase a Premium Disc for one Curio. You can also earn free gems by completing the in-game offers or watching advertising videos by selecting the "Free Gems" button in the store.
Skill set
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.
