I don't know if this doable in the code right now.
The concept of Gamble keyword is all about being random.
So it's possible to put Tribute / Blackmarket into Gamble in the future!

Gah, I don't like the prospect of "All or Nothing" at all. It doesn't seem right that an entire match can be played just to have it decided by a D10 roll when one player is finally backed into a corner. Desperation moves like discarding everyone's hands or trading cards at random can be exciting, but not this. It would be a pyrrhic victory for either side -- a successful play of it would be a win that wasn't earned, and the more likely losing gambit would rob the opponent of the final, crushing play.

There are also the proposed changes to consider regarding points earned through a game. What classification of victory is this and worth how much?

(continued)

I know that there are cards that grant instant victories, but the conditions for their uses are so specific or expensive that the opponent has several ways to prevent their use aside from a forced discard. The same goes for Last hope and its resource comparison conditions.

I don't mind the Gamble keyword suggestion as a whole. It could certainly make for an unpredictable match. I just don't think that one free card should have the power to decide the game without any influence from the status of both players.

I like this idea, also golden scepter and magic lamp could be considered "gamble".
I agree with DPsycho about "all or nothing", what about something like "90% defeat, 10% tower = 30 wall = 20" ?

It's funny.

If ever implemented it will need some more thinking and ballancing, but...

It's funny. ;-)

Could you clarify the Wheel of Fortune effect?

The function for Wheel of Fortune is to randomly swap/exchange 2 stock(bricks, gems, recruits from both players)
So basically there are 3 functions include:
Swap one of your stock with opponent stock (say exchange your bricks for opponent gems)
Swap two of your stock (say exchange your own bricks for your own recruits)
Swap two of opponent stock (say his exchange his own gems for his own recruits)
I hope it makes sense

In order to make these cards worth it, the effect for you has to be worth about twice (or more in some cases) what you're paying for it. For example, your small tower adjustment card should look more like:

Free:
50/50 chance: -5 your tower or -10 opponents tower.
