Who would win, Thassa Oracle combo vs one Anticognition?

So dude is playing a treasure hunt Thassa Oracle land deck combo on me. Three treasure hunts in on turn 4, at which point I've only played 3 lands, he's ready to play Thassa Oracle and take his win, "good game" I say before he casts it with his last 2 mana, not knowing he won't get the chance. Dude scoops before it even resolves.
