Collectible Card Game Headquarters

Describe the Bug:
When the AI casts Power Sink, the popup that displays always says that X is 0. This is purely a display bug; Power Sink still works.

Which card did behave improperly ?
Power Sink

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
KOT, duel

What exactly should be the correct behavior/interaction ?
The display when Power Sink is cast should tell you how much was spent on X, not 0.

Are any other cards possibly affected by this bug ?
Other cards with an X casting cost.

Well, it seems the engine looks directly in the 'x_value' variable to display correctly the X value. It was automatically zeroed for avoiding unwanted interactions between cards like Green Sun's Zenith and permanents with X in the casting cost, but I see this is fundamentally wrong, so I reverted that part in 378315b and modified Green Sun's Zenith and Wargate.
There are others instant / sorceries with X in the casting cost that puts into play permanents ?

Don't know if the distinction matters, so also including cards that put tokens into play.
