Did you have a favorite deck? I like the Naroom, Adriel and Weave Decks.
A lot of the people I've played the game over LACKEYCCG with keep using CORE decks; and it's become very... unplayable. I mean, CORE nation cards are good; Over powered even; but when people on the clients I've been on have access to ALL of those cards; the game is over in a matter of turns before it begins.
Whats more is the guys behind Magi Nation and how they ran their IP into the ground. They were doing well continually printing the card game and had a great magazine printed for their whole world built around the card game; even though the magazine only ran 1-3 issues. Than ran the whole thing into the ground by attempting to expand to other forms of media instead of attempting to get other shops and stores to carry their game. they stopped printing the card game back in 2002 or 2004, I can't remember well, and re-surface with a TV show back in 2007. The opening theme was great, though I didn't care much for it being a kids show; even then there were dozens of changes made to the show that broke off from the original lore. The Core Glyph being a giant ball with gems in it than being a simple, portable disk, Tony Jones going from Blonde to Brunette, Changing the use of rings to carry dream creatures to just chunks of rocks...
The developers of the IP were hoping Cookie Jar Entertainment would help re-print their card game with the TV show in place, but that died before it even took off.
