Well, without knowing anything about Tripe Triad, I would say that making a COMPETITIVE card game based on rogue-like mechanics and randomization would probably not be fun to play as there would be too much of a chance that the randomization gives one player a distinct advantage over the other. As soon as players realized what kind of scenario they were given, they would have a fair idea of how the match would go in the metagame and it would be over before it began. The more you move away from that, the less it carries the characteristics of a rogue-like, so all in all, my first instinct is that the two types of gameplay just aren't really designed to be synergistic.

However, creating a rogue-like card game that is single-player might prove very interesting. Card mechanics are essentially the same as "normal abilities" except that you have 1) usually more complex arsenal/loadout/ability organization and strategy, 2) don't have access to all skills at once, 3) must rely on luck/probability, 4) must adapt to an unpredictable and dynamic play capacity, all of which may be in favor of development in a rogue-like system.

The thing to be mindful of in that case would be ensuring that players feel as though the game is based on their skill and intellect rather than the game is just screwing them over with bad luck. The player should always feel like they had all the tools and knowledge they needed to evade, counter, or defeat any threat that is posed at them.

i've done card type games in the past. rapid prototyping is really called for when inventing a new card game. IE try it and find out.

what would you think of a random card game ? Something like a rogue-like card game..
Any remarks ?

Triple Triad is the CCG minigame in Final Fantasy 8. It's not even remotely balanced, because it's intended for the player to win a lot against NPCs. It is also too simple to fly as a competitive card game like Magic or Yugioh or something like that. It was quite popular as a single-player minigame though, and I think it would work fine as a casual multiplayer minigame similar to poker, spades, heart, or dice; might have to remove the ability of players to lose cards so they didn't get trapped in a spiral of losing though.

Something like a rogue-like card game

I dont know about the triple triad thing, but Hand of Fate is something like a rogue-like card game. The action fighting part isn't anything special, but I love the mood of the card game. Cards are laid out face down, and you move through them like it's a map, each space revealing an encounter of some kind.
