@fsecco Sure, you can choose to play more counter spells in your Oath deck such as Pyroblast and Misdirection. You can also use Merchant Scroll, Demonic Tutor, and Night's Whisper. These cards allow you to defend against your opponents sorcery of instant speed blue spells by waiting with Mission Briefing to cast a Force of Will, Flusterstorm, Pyroblast, or whatever counter spell you might have. The tutors allow you to search up an instant speed cantrip, or whatever else you might need, and threaten to cast it again at instant speed.
I typically did not play Gitaxian Probe, but the options stated above have incentivized me to do so. These play patterns give you more options to combat Paradoxical Outcome without requiring an artifact that is potentially counterproductive to Oath's strategy. It is basically the Snapcaster Mage effect that the deck needed. The ability to cast more counter spells like Pyroblast and Flusterstorm is especially good against Teferi Control decks. The new creature card Emissary of Grudges is also a really good sideboard option against this deck.
