Hello.
Me and my friends seem to have a bit of a trouble, and that is support abilities.
For example, someone just activates Xykon on the 4th floor. That means 4 monsters +1 for leader +2 for horde because of the 3 demon roaches already on the floor.
Now we start placing monsters, we all place goblins and undead, in the end there are about 20 monsters and Xykon has 54 in attack and defense!
The only way I can see that can possibly defeat him is "I forgot they could to this" card, if it works on support abilities, which I'm not sure off.
Any help would be great!
