Swarm Intelligence Rulings

  • Jul 14, 2017

    If the spell has damage divided as it was cast (like Chandra’s Pyrohelix), the division can’t be changed (although the targets receiving that damage still can).

  • Jul 14, 2017

    If the spell that’s copied has an X whose value was determined as it was cast (like Torment of Hailfire does), the copy will have the same value of X.

  • Jul 14, 2017

    If the spell that’s copied is modal (that is, it says “Choose one —” or the like), the copy will have the same mode. A different mode can’t be chosen.

  • Jul 14, 2017

    Swarm Intelligence can copy any instant or sorcery spell, not just one with targets.

  • Jul 14, 2017

    Swarm Intelligence can copy the spell even if it’s countered before Swarm Intelligence’s triggered ability resolves.
