Mystical Dispute's discount never applies here since none of their spells are blue, but it still counters any spell unless they pay 3, which can be hard for them to pay when they tap out for a big Eldrazi like Devourer of Destiny, Emrakul, or Kozilek's Command. Fatal Push whiffs on their biggest threats (Emrakul, Devourer of Destiny, Sire of Seven Deaths) and only reaches Sowing Mycospawn when revolt is on, so it is weak here. Surgical Extraction can strip a key Urza's Saga-fetched artifact or a copy of Ancient Stirrings/Malevolent Rumble to slow their engine. Keep Leyline Binding in as your main interaction since it exiles any nonland permanent regardless of color, and keep Lightning Bolt in to handle their smaller creatures like Basking Broodscale.

Rakdos Delirium plays Thoughtseize themselves and operates on a grindy graveyard plan (Stitcher's Supplier, Street Wraith, Nethergoyf, Detective's Phoenix), so mirroring their discard is low-value while Surgical Extraction can exile a key graveyard piece like Nethergoyf or Detective's Phoenix once it hits the graveyard, stunting their delirium engine. Obsidian Charmaw gets no cost reduction here, because none of their lands can produce {C}, so it is a full-price five-mana 4/4 flier. It still flies over most of their creatures (Detective's Phoenix is the main exception) and destroys a nonbasic land on entry, and they have plenty of targets in their fetch-heavy manabase, such as Blood Crypt and Raucous Theater. Trimming the Thoughtseizes and Practiced Offense for proactive bodies and land disruption is reasonable against a deck that does not rely on a single hand-based plan. Keep Lightning Bolt and Fatal Push in as cheap answers to Orcish Bowmasters and their small creatures.

Esper Control is loaded with blue spells (Narset, Teferi, Jace, Day's Undoing), making Mystical Dispute a cheap, efficient counter against their key draw-sevens and planeswalkers. Thoughtseize and Fatal Push are weak since their key threats are often protected by flash or are planeswalkers/enchantments Fatal Push can't touch, and discard is less reliable once they're holding up Solitude and Force of Negation. Surgical Extraction can strip a copy of Solitude or Teferi after it resolves once to deny future copies, and High Noon slows their ability to both develop their control plan and interact in the same turn since they rely on stacking disruption. Keep Stubborn Denial and Leyline Binding in as your primary proactive disruption against their sweepers and planeswalkers.
