Beseech the Queen, Demonic Collusion , Diabolic Revelation, Diabolic Tutor, and Increasing Ambition all tutors for setting yourself up or looking for a utility card to screw someone over
But, you need to remember that high level tournaments (either constructed or limited) are not the only formats played
I probably wouldn't want to face any random player using these cards, but as the man who both invented the game and designed the entire Arabian Nights set by himself, he clearly gets a pass to make the cards he wants for his old school deck
You can only activate 1 "Foolish Burial Goods" per turn.
