The longest-running continuously-in-print collectible card game is Magic: the Gathering.
The second longest-running continously-in-print collectible card game is not Pokemon, not Yu-Gi-Oh, but Redemption CCG, a game that looks like that.
Illustration credits range from Mark Poole (of MTG fame) to Raphael (of "School of Athens" fame). Cards have text like "If used by a flood survivor or evil antediluvian". There's a rules-meaningful difference between a card being green, teal, or pale green. The order of continuous effects is solved by partitioning all abilities into "rock", "paper", and "scissors", with the winner of that RPS applying first.
Best of all, the Third Edition rules tell us "If you have a question, please look it up in your Bible. Read all relevant verses given in Scripture. If you find any mistakes, please write and tell us."
