In reference to this unanswered question about Circle of Steel.
According to the "Terrain" part in the Glossary, since all Terrains in play are discarded immediately after battle resolution at the battlefield that just resolved, and since a Terrain's effects with a duration end if it leaves play, do these two rules imply that Circle of Steel's last effect can never be applied, because it is an effect with a duration ("until your next turn ends"), therefore it always ends a few seconds before applying ? If no, why please ?
Thanks for your explanations.

Any effect produced by a Terrain card that produces an effect that has a duration that explicitly extends beyond the point where the Rulebook would eliminate Terrains invokes the First Cardinal Rule in that instance.
This does not change how the Terrain functions when it it is removed from play by any other means (such as a card effect). If Circle of Steel is destroyed or removed from the game before its Delayed Effect clause is applied ("After this battle resolves ...") the Delayed Effects are never applied - just like a "normal" terrain's Delayed Effects that would normally come before the Battle Resolution aren't applied if the Terrain is destroyed before their timing window.
