  • WotCNov 12, 2019

    An effect that increases something by a specific amount (such as the first ability of Jaya, Venerated Firemage) isn’t doubling, even if the result is double the normal result.

  • WotCNov 12, 2019

    An effect “doubles” if it instructs a player to double something, or if it replaces an event with “double that much,” “twice as many,” or similar.

  • WotCNov 12, 2019

    Double strike isn’t an effect, so it’s not doubled.

  • WotCNov 12, 2019

    If two Maro’s Gone Nuts are on the battlefield, effects that double instead octuple. If three are on the battlefield, effects that double instead sexdecuple, and so on.
