Andrea Mengucci played Turtenwald's 75 in a legacy league:

I like the list, delver and dazes solves the biggest issues this deck type has IMO:
1) how to not lose to fast combos during the first turns and
2) how to deploy cheap efficient threat without risking to lose next turn if you dont have FoW.

Maybe Jaces could be in the SB and Path to Exile and Council's Judgment in the MB to get the instant/sorcery count a bit higher for the delver flips?
