Post-DRS and Pre-War was the best positioned the deck has been possibly ever. A lot of the top decks were very favorable - UW Miracles, Grixis Control, Stoneblade, Grixis Delver, Depths, DnT, Lands. War and Modern Horizons introduced Narset, Blast Zone, and Force of Vigor. Narset meant that any blue deck, which used to be very favorable, suddenly had an insanely powerful hoser MD, Blast Zone meant that any deck with Crop Rotation had a cheap out to Elephant Grass, and FoV meant free removal in a whole swarm of decks. In addition, although level 1 analysis might say that Oko doesn't hurt us, the truth is that it killed a lot of our best matchups, especially Grixis anything, Stoneblade, and DnT.
