They implied it when they released it as part of the Witch of November II pack, and mentioned something along the lines of "this is your last chance to get these cards before they disappear!".

Obviously Slayer and other cards part of that pack are still in the LCP, so they're not currently extinct, with the exception of Styx. Who knows if they'll ever be extinct. For all we know, maybe those cards being in the LCP is a result of a mistake on their part.
