I strongly disagree. The advantage given in even a single battle isn't strong without knowing your opponent's deck. So they are able to form the shrieker rush of their choice. If their opponent happens to have a deck that counters it, where is the advantage?
With all cards at your disposal, you'll have to be very careless or very unlucky to lose to a person with 60-90 cards (30 of which you already know). Yes, it's just a single battle. Yes, it's not worth much when you already got lots of cards. But you are thinking too long term. Water players would capture the Wonder early, and harass the neighboring element hard and fast. With just the right amount of teamwork, the neighboring element can easily become feeder towns for Water.
A movie has no bearing on this game and shouldn't be mentioned.
This is very biased and immature. I don't see why a movie can't be mentioned. I can only surmise that you did not understand the post or you simply didn't want to. A lot of games draw inspiration from movies, myth, books, real life, other games, etc. Anyway, to put it more simply, I'll give you an example. Heroes of Might & Magic is a totally different game and is completely unrelated to Elements. However, since it was agreed that the Wonder concept used in that game would be a great addition, it has now become hugely related to WoE. If it wasn't used, Wonders would easily have no bearing in this forum. The same applies to other ideas. I hope you can finally understand with this simple analogy.
