Collectible Card Game Headquarters

Whenever the opponent plays Doom Cannon, I get a crash with the following error message:

Abrupt Decay played by AI exiled my creature instead of destroying it.

Please read Disrupting Shoal closer, it's a Spell Blast -like effect, not a Power Sink effect.

Did your opponent have a Kalitas in play (or something else?)

this is what it looks like

I believe you need to Ctrl+Click to select both colors.

Ups! My bad Don't know why I did not think of that..... Sorry. Works perfectly

My apologies, I must have been too tired or something.
I will think (and check) twice before polluting the forum next time.

All the best!

Also, Belbe's Portal.

Known issue, fixed in trunk.

Vesuva entering as Cavern of Souls doesn't give me a choice of creature type.

Demon-Possessed Witch 's transform trigger activates each time Kindly Stranger attacks for each enemy creature on the board.

Having delirium is not necessary for the effect to trigger, attacking into an opponent with creatures on the board is the only requirement.

The card mind's deletion does nothing. It's effect is triggered, but The top card of the player's library is not exiled and you can't cast anything.

Mind's Desire works fine for me. The card IS exiled and is available to be cast whenever you want.

Mind's desire is working fine too. but I'm talking about mind's dilation. The enchantment not the sorcery.The enchantments not this sorcery

You said Deletion, so it wasn't very clear what card you meant.

Anyway, that seems to work just fine for me too, not sure if it was fixed more recently than this release. Can you provide more details? Please read the link in my signature for what specifically we're looking for.

Hi.

I can't get Forge to start at all. Attempting to start the program produces the error dialog box attached.

PS: I have just reinstalled both Java 7 and Java 8 32-bit runtime environments also (my main JRE is Java 8 64-bit). No dice.

I've been having this problem too last couple of releases - think the problem came out just after I installed Java 8. Are you running the .exe? I can run the .jar fine, but can't get the .exe to run.
