原文If you control more than one Oracle of Mul Daya, the effects of their first abilities are cumulative. If you control two, for example, you can play three lands on your turn.
原文Oracle of Mul Daya doesn't change the times when you can play a land card from the top of your library. You can play a land only during your main phase when you have priority and the stack is empty. Doing so counts as one of your land plays for the turn.
原文If the top card of your library changes while you're casting a spell, playing a land, or activating an ability, the new top card won't be revealed until you finish doing so.
