Dimir Tempo brings heavy disruption with Thoughtseize, Force of Will, and Daze, so the extra Veil of Summer is very strong, protecting our hand from Thoughtseize/Fatal Push/Snuff Out and letting our spells resolve through Force of Will since 'can't be countered' still lets us dodge Daze's mana tax and blue removal on our own turn. Our Force of Will and Flusterstorm are important to protect our Show and Tell or Omniscience from their countermagic. Play around Wasteland threatening City of Traitors and single-color-source lands, and try to combo before Murktide Regent or Tamiyo generates a long-term clock.

Eldrazi is a colorless-heavy deck built around Chalice of the Void and big colorless threats like Thought-Knot Seer and Reality Smasher, making Consign to Memory excellent since it counters colorless spells and their triggered abilities (like Thought-Knot Seer's ETB). Chalice of the Void set to 0 or 1 is a serious problem for our cantrips and Lotus Petal, so try to play around it by holding Ancient Tomb-fueled bigger plays. Into the Flood Maw can bounce a Reality Smasher or Thought-Knot Seer that's stopping our combo. Spell Pierce is weak here since much of their deck is creatures.

Ocelot Pride Midrange's disruption is entirely Thoughtseize/Cabal Therapy plus white removal like Swords to Plowshares, with no blue spells at all, so the extra Veil of Summer protects our hand and gives us hexproof from black targeted effects during our combo turn. Wasteland and Karakas are annoying against City of Traitors and our legendary payoffs, so sequence lands carefully and hold Force of Will to protect Show and Tell or Omniscience. Their deck is proactive and can race us if we stumble, so prioritize a fast Show and Tell into Atraxa or Emrakul rather than grinding.
