Eh, I knew how to play when the game came out, but I always thought it wasn't really that great. Similar to MtG, I don't like filling up a third of the deck with resource cards that would be dead draws by the tenth turn. I'm also not a fan of a rotational ban list, though it definitely is better for game balance. I honestly don't think that this game would have lasted as long as it has without the brand name.
That being said, I do like Yu-Gi-Oh, though that game is majorly suffering from a huge power creep problems.
It's not nearly as resource heavy as it was in the beginning, were you'd need a fuckton of energies even if the attacks were low-powered. You'd never see this kind of card in the modern tcg
4 energies for a measly 50 power attack with no secondary effects? bleh
