当亡桥吟颂进战场时,将你牌库顶的十张牌置入你的坟墓场。
在你的维持开始时,从你的坟墓场随机选择一张牌。如果该牌是生物牌,则将之放进战场。若否,则将其置于你手上。
Each card in your graveyard must have an equal chance of being chosen. Assigning them each a number and rolling a die is an easy way to do this. In formats that allow you to rearrange your graveyard—including Standard, Modern, and Return to Ravnica block Limited formats, you may also shuffle your graveyard face down and choose a card at random.
