I don't have much exp with the deck and my SB is still fluid since I want to find the right configuration. However I think some things are pretty much standard!
4 push out vs control, side in x Dispute/Flusterstorm x Narset
4 push out vs Tron side in x Spreading seas +(maybe a discard effect or extra win con or an Ashiok at worst)
Vs vial decks Remands are out, side in removal choice of preference and mass removal too. My list has 2 Legion's end, 2 CoBru
Vs Prowess depending on the color comb we can diss a number of Jaces, maybe some discard and some remand to side in removal, CoBru and counterspells (if UR prowess, dispute and so on)
Vs GBx and Shadow we can sit h discard and add spot removal, aether gust (depends on the matchup), (plus maybe some ashioks and seas, depending on how many discard we want to ditch)
Vs 4c Bring to light/scapeshift aether gust is great over maybe some relics, CoBru is also a good option.
Vs Amulet Titan, I think Spreading seas is a trap due to having bouncelands, so Aether gust and Ashioks should be enough over maybe some spot removal and Relics
