Kor Haven, makes you invulnerable after using once

[GoogleCodeExporter]

After using it once to prevent damage from a single creature, seems that it
made me and the AI invulnerable to further damage, as the life totals
wouldn't drop an inch even attacked by a horde of 8/8 Angels (like 20-30).

Using Wagic 0.10.1.

Confirmed. We have 7 cards which use code of this format (or similar):

preventAllCombatDamage from target(creature) ueot

This can't work because the parser looks for "from(", not for "from", and this 
probably 
screws up the parsing so that the ueot won't get parsed correctly. Which leads 
to an 
untargeted, unconditional, infinite damage prevention.

I'm not sure how preventAllCombatDamage is meant to work for such cases. The 
"from" does 
need to be immediately followed by an identifier enclosed in parentheses. This 
identifier 
can only by "this" or "mytgt", anything else won't work. Specifically, 
from(target
(creature)) will not work: You can target and select the creature, but the 
effect won't 
be applied to it.

We can get around that limitation by adding a separate target specification 
like this:
auto={1}{W}{T}:target(creature[attacking]) preventAllCombatDamage from(mytgt)

This will add the effect to the targeted creature, but it won't be removed at 
end of turn, 
not even when we add "ueot" to the rule.

"from(" works like "target(", so instead of from(target(creature)), we should 
write 
from(creature). I don't know if that's your only issue here?

from(creature) will not allow to specify a target, instead the effect will 
affect 
all cards that meet the specified criteria. The effect will also last 
indefinitely, even if ueot is explicitly added. So that's unfortunately not the 
solution.

the ueot issue is a different problem. For the time being we should remove these
cards that say from target..., and open a different ticket for ueot issues

Removed Kor Haven and other similar cards from the SVN.
Please open a new issue for any other "prevent damage" bug

No, it's been removed from the game for now. That's why the status says "Won't 
fix"
