Superboy #140

A den of well-dressed gamblers crowds around a table stacked with money and chips, while their ringleader gleefully offers 10-to-1 odds that Superboy — visibly straining against a glowing Kryptonite trap on a railroad bridge — can't free himself in time to save an oncoming train. The cover tagline promises readers an introduction to "Lucky Lucifer — The Gambler Who Never Loses!", setting up a villain whose confidence is clearly as outsized as his bankroll. With cover art by Curt Swan and George Klein bringing that crisp 1967 DC polish to every detail, this is a thoroughly fun premise that pits the Boy of Steel against someone whose weapon is calculated certainty rather than brute force.
