Since VD cost only 2 you have the chance to add a cloak wich could prevent catapult to be stolen/destroyed, also what to do if catapult came last card?
Good idea about the cloak, what would you suggest taking out for it?
About the last card, it will happen in 1 of 30 games on average, so that's not a problem.
Good question here, i really don't know, is such a delicate mechanism in both versions.
Almost every card is needed for the combo to be succesful, so maybe 1 prec. in the unupped and 1 tower in upped, but it doesen't convince me that much, maybe the only way to insert it is just to add it and go 31.
