7 rulings from Wizards of the Coast
- 4 October 2019The cost reduction ability reduces only the generic mana in Emry's cost. The colored mana must still be paid.
- 4 October 2019You'll still pay all costs for a spell cast this way, including additional costs. You may also pay alternative costs if any are available.
- 4 October 2019If Emry's last ability targets an artifact land card, you can't play it. Effects that allow you to "cast" a card don't allow you to play a land card.
- 4 October 2019To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Emry). The mana value of the spell remains unchanged, no matter what the total cost to cast it was.
- 4 October 2019Once you announce that you're casting a spell, no player may take actions until the spell has been paid for. Notably, opponents can't try to change by how much Emry's cost is reduced.
- 4 October 2019You must follow the normal timing permissions and restrictions for the target artifact card. Unless it has flash, you'll most likely only be able to cast it during your main phase while the stack is empty.
- 4 October 2019Casting the target card causes it to leave your graveyard and become a new object. You can't cast it again if it returns to your graveyard this turn.
