Волшебство
Сбросьте вашу руку. Возьмите семь карт, затем сбросьте три случайно выбранные карты.
You discard your hand as part of Drastic Revelation’s effect, not as an additional cost. If you have no cards in hand at this point, you simply don’t discard any; the rest of the spell will still have its effect.
