UR Aggro's Slickshot Show-Off grows off noncreature spells and Eddymurk Crab has an enters-the-battlefield tap trigger, so Spider-Sense counters their key cantrips or disruptive triggered abilities to blunt their tempo plan. Clarion Conqueror is a 3/3 flying blocker that survives an unkicked Burst Lightning but dies to a kicked one. It also turns off activated abilities of artifacts, creatures, and planeswalkers, including your own Curious Farm Animals and Zack Fair. Springleaf Drum (an artifact Conqueror would shut off anyway) and Nurturing Pixie don't hold up well on defense against their aggressive curve, so prioritize bodies that trade well and disruption that protects your own threats.
