5* relics that are not part of the current banner have either a 0% chance of being drawn or something like 0.001% chance of being drawn. So don't waste mythril trying to get the Ice Whip or Mythgraven blade. Sazh's gun for Boon is one of the ones available from the Lightning banner and that'll be at ~1% chance per pull.

For those old relics you need to wait for the Soul Break celebrations they do every now and then that re-offer them, or hope they show up in one of the upcoming banners. I don't think there's an FFIV event coming up so I doubt those two would be coming before the next celebration.
