We had the same discussion about my enforced recruitment concept (just the same with other numbers and working for only yourself:

All in all, it has to be said that this card would be one of the few recource finisher in the game, i like this concept even more than my own, because its affecting both player, making a counter strike possible.
the point of this card is that you need to make it finish the game, else, you have just 1/1/1 facilitys (everyone who plays against plague sometimes knows what i mean). And then, a recource victory will be very hard
