These two combined are an incredibly oppressive first-turn board that can catch many opponents off guard and winyou some games
What does Prophecy Destroyer do
I'll be honest, a lot of people hate this system, as it leads to a lot of games where you can't do anything, either because you didn't draw enough lands, or because you drew too many with no cards to use them with
You can Tribute this card you control and 1 each of "Kuribee", "Kuriboo", "Kuribeh" and "Kuriboh" from your hand and/or field
Expensive cards arent risk-free, of course
Maybe you dont need a board wipe right now, but you do need to remove that Consecrated Sphinx before it draws its controller too many cards
