This matchup is primarily about managing their go-wide token and blink engine — Ocelot Pride and Guide of Souls generate a lot of board presence quickly while Ephemerate and Phelia repeatedly rebuy enters-the-battlefield effects. High Noon is your best tool here, limiting them to one spell per turn and completely neutering their Ephemerate-based blink sequences. Bring in the additional Wrath of the Skies as a third sweeper alongside the two Supreme Verdicts and two maindeck copies, since their white creature flood is the primary pressure vector. Mystical Dispute comes in primarily to answer post-board Consign to Memories (they'll have four total), as well as their own Teferi, Time Raveler which would otherwise strand your Counterspells. Counterspell is trimmed by one and Flow State and Lorien Revealed are cut as the lowest-impact cards against an aggressive creature strategy where you need live interaction and sweepers rather than draw smoothing.
