I'd suggest you put the "meta deck" section into your wiki, and update it frequently, to promote the uniqueness of your wiki.
You can even link the cards in the decklist to the main wiki! (temporarily, ofc)
You can find the current meta deck + their decklist here:http://forum.lightmare.com.au/index.php?topic=66582.0
you can always allow ppl to add more deck if the deck is <tier 3
For tier 2/1 it can only be added by permitted users (or only yourself)
Overall, nice work.
