Here is one of the most anticipated reprints from the original Theros set. Gray Merchant of Asphodel has been one of the most valuable cards in mono-black Modern decks for a very long time, and it will do just as fine in the current Standard season.
Devotion decks will find it to be an incredibly efficient finisher that will synergize with Command the Dreadhorde enchantment, which puts creatures from your graveyard back onto the battlefield.
When you have enough black mana for the Merchant, play it and win immediately.
