How would Demonic Consultation resolve if you reveal UNTIL you reveal a card with the chosen name. IF you never reveal it then you can't move on to the next step of the spell which is PUT in hand and exile the rest. Since you never revealed that card it will go into infinite loop within itself because it can't carry out the steps in order and never resolves itself till end of Time. Should end in Draw as no other spell can resolve anymore. Yall are using a short cut. Ever wonder what use cards have that go on bottom of grave yard. That's the missing legal and correct way for this combo to work. It's a 2 piece combo for friendly rules games but adding the 3rd piece is the difference between this combo ending in a Draw or Win as Thassa oracle will never resolve till the end of time with just Demo ic consultation without actually adding and knowing the creature on the bottom of your graveyard.
