Tips and Tricks
In the game rather than controlling your character directly, you issue attack commands through a series of cards issued to you randomly in a deck.
Build up as many combos as possible because by putting together three or more cards in a row, you create a more powerful attack card that pretty much guarantees severe damage to your opponent.
If you see cards in your deck that are alike, such as the High Slash cards, try and form a combo where they eventually pair together, putting ones in the way in your attack line. They will then join up and give you an opportunity to strike back against your opponent in a stronger manner.
By adding friends to your roster, you'll run into a better opportunity to swap medals with them, and amass a collection that you can add to your character profile. The more medals you carry, the more people will take notice and you'll get even more friend requests.
Reinforce lets you merge cards into characters to level them up in various areas, mainly attack and speed. This will also sacrifice older cards so you can make room for new ones.
Resonance will increase your ability to gain rarer cards for your character, while at the same time clearing away older ones no longer of use, such as repeat weaponry. Try these out and you'll see the skills of your fighter exponentially improve.
