So I just had an interesting match. My opponent was playing an Abzan angels/graveyard recursion deck, I was playing a Grixis Foretell deck. My opponent gets Elspeth Conquers Death out, I play Tegrid's Lantern. Next turn I top draw Tegrid, and play her. Third lore counter goes on ECD, and opponent brings back Kaya (Kaldheim). Tegrid triggers from ECD being sacrificed. I put it on the battlefield under my control and exile Kaya. My opponent scooped.

So Tegrid is now on my list of soft counters for Sagas.
