card games cards are very hard to balance, so how about
we make things the other way round.
perhaps there will be non-pvp cards, if you are afraid
of your "new" cards destroying the pvp.
or maybe you are thinking if actually non-pvp cards
would also destroy the pve, as some players would find
some imba comboes,
then how about "Trial Cards",
Trial cards are the new cards that might be imbalance
you put into the game,
Trial cards can only be used in
Trial Matches - random battle
Trial PVP - PVP
Trial missions - doing quests
Trial PVE - grinding AI
and so on....
why Trial cards won't kill the game?
because when you use trial cards, you
are limited to play in the trial format
which you gives like 20% exp, 20% gold
of normal games.
and it doesn't change your victory scores.
Trial game are more of a fun and exciting platform to
try out new comboes, test new cards.
which will cetainly boosts your game popularity with
those players that have play the game to the point
where there is no novelty or surprises blablabla in the game.
just let us play new caaaarrrrghhh...
