There were only 1,000 Seers released per country. However, they were only released in Australia which means that there are only 1000. Each one was individualy numbered. Seer is neither a hyper, a shadow or a crystal.
Seer is worth 15 points, which is the second highest point ranking, losing only to Xar, who has the same number of points, but has an extra 5 points for a face-down, where all other characters get 0 points.
Seer is the one who prophesied the downfall of Xar. Hence the series 2 name "The Prophecy."
