Auspicious Arrival

Reveal the top ten cards of your library. Put a Sliver card from among them into your hand, all other creature cards on top of your library in a random order, then the rest into your graveyard.
Desperate Hour - If you have the fewest permanents on the battlefield, cards in hand, or lowest life total, Auspicious Arrival has Flash, Convoke and Buyback {w}{g}.
Through the rift they poured, and our fate was sealed.
