The problem with this game, is the abuse of players toward certain cards that make the game itself ends up being repetitive, you find decks of type "death" is based only boneyard and bonewall nen, fire decks only based on spirit fire, and so consecutively, ie you see a deck type, and you know exactly how it will play ... bored :/
ademas, me parece ridiculo, que me meta a una mazmorra de nivel 1, con nivel 7 y 3 personajes, y el boss sea mas fuerte que una mazmorra de nivel 2, de la propia historia...me parece de lo mas absurdo de este juego, ademas de el hecho de no poder vender los objetos inutiles.
Forgive my grammar, I am using a translator, because they do not speak English, I'll post some suggestions:
1 - improvement could include more speed gun in the attack, defense and improvement of a certain percentage of damage reduction.
2 - could have different characters, each with different weapons and armor diferenes
3-level up the character could improve a little something
These are all suggestions I can think, that if the game is very good ^ ^
