This is an Eldrazi ramp-combo deck trying to power out Emrakul, the Promised End and Devourer of Destiny off Eldrazi Temple and Urza's Saga; Toxic Deluge sweeps their small Basking Broodscale, Glaring Fleshraker, and Eldrazi Spawn tokens while dodging your own big threats if you tune X low, and Damping Sphere punishes both Eldrazi Temple's and Ugin's Labyrinth's double-colorless output. Pithing Needle can lock down Urza's Saga's Construct activation or a key activated ability like Basking Broodscale's adapt. Inquisition of Kozilek is weak here since their curve tops out well above 3 mana with expensive ramp payoffs, and Orcish Bowmasters is a low-impact 1/1 against a deck full of bigger bodies and spells that trigger it far less often than you'd like. Keep Thoughtseize and Fatal Push in as your best interaction against their ramp pieces and small creatures.

Izzet Prowess floods the board with cheap threats like Dragon's Rage Channeler, Monastery Swiftspear, and Slickshot Show-Off, so Toxic Deluge is your best sweeper to reset the board even at a modest X since most of their creatures have low toughness. Dismember gives you another cheap, efficient removal spell that can be cast for as little as {1} plus life against their aggressive clock. Inquisition of Kozilek is worse than Thoughtseize here since it can't strip anything above 3 mana and their deck is stocked with cheap burn and creatures your life total can't afford to ignore; Mishra's Bauble is low-impact against a fast clock. Keep Fatal Push and Thoughtseize as premium interaction, and prioritize racing/removal over card selection.

Esper Blink relies on ephemeral value creatures like Flickerwisp, Phelia, Exuberant Shepherd, and Witch Enchanter, plus Overlord of the Balemurk and Solitude for card advantage and removal. Wasteland Strangler gives you a proactive threat that can shrink one of their key blockers or attackers by -3/-3 when it enters if you put an opponent's card from exile into their graveyard, which is relevant against Phelia or Flickerwisp. Dreams of Steel and Oil is a discard spell that also strips a card from their graveyard, hitting their Overlord of the Balemurk or a stranded Flickerwisp in one shot. Mishra's Bauble and Pithing Needle are fairly low-impact against their resilient value engine since they don't have a critical activated ability to lock down. Your discard suite (Thoughtseize, Inquisition of Kozilek) remains excellent at stripping their key enablers before they can chain value.
