Basically, I would lean on the Charm and Cage to basically tag team do what Plague does, but against more decks and be more broadly applicable.
-1 Duress shouldn't be bad, because in a control match up, you'll have 2 Duresses, 3 REBs, some number of Thoughtseize and Hymn to Tourach and Liliana. So losing 1 Duress shouldn't mess up those matchups too much vs the value gained from Cage shutting down Elves!, Reanimator, Past in Flames Storm chains, and Dredge variants.
