i meant about strategies, but here we go.
As Im trying to build a card game with no expansions the game wont be centered about creatures but really the player itself.
(as it is known that the creatures are a modification and a personality of the player that is in constant change(both).
The concept of the game will be the principles.
Using all the 10 of them every card will be divided as a principle, hving a set ammount of them in the entire pack.
As in the real game u often trade the force of ur creatures for a better profile, the game tries to copy that ever changing concept.
Both players will hv stats divided in 3 types(atk, def, power).In the beggining everything is zero.
The principles too will have their qualities divided in these 3 main types.
For the player to up his stats he will "use" one of their principle cards and put on the principle respective stat type(can be done one time per turn).
The player life force is called Energy, with it the players can use the combo power of the principles, and if it ever drop to 0 u loose. its their life and mana at the same time.
Altough it doesnt cost u life to turn principles into stats, it cost greatly to use the principles combo power as u are really "using/destroying" that ammount of principle. Every principle has a combo set, and a different one when combined with another principle for a greater cost. Principle combo power can be used too from the players stats.
Power is a one time use stat that u can "use" it to change the number of a combo power to +1 or -1.
Example:
Principle of light power: (+2) Energy Points.(Life Burst)
Principle of darkness power: The next(1) card the opponent would get, he cant see it and has to play with it without knowing it for X turns.(conceal card)
Combo light-darkness power: Hide (+2) Energy Points of the opponent or yours for X turns, function like they had lost and then regained.
Still in development but there are some concepts like, for every one with 15+ Ep he gets -1 energy point each turn and if 5-, then +1.
PS: didnt tell everything, and my head is a mess right now, trying to put everything on paper but its hard.
