Encarded decks do not follow the standard mold. They are not plain, they are not boring. They come in limited numbers, and will never be made again. Each one explores new ideas, new design concepts, new themes and pushes the boundaries of card design way beyond the norm.
If you want a truly custom deck, one that will be a jewel in your collection but also handle supremely well and be usable for play, you can't do much better than an Encarded deck.
