Comprehensive Rules (April 17, 2020)

  • 701.38. Exert
    • 701.38a To exert a permanent, you choose to have it not untap during your next untap step.
    • 701.38b A permanent can be exerted even if it’s not tapped or has already been exerted in a turn. If you exert a permanent more than once before your next untap step, each effect causing it not to untap expires during the same untap step.

    • 701.38d “You may exert [this creature] as it attacks” is an optional cost to attack (see rule 508.1g). Some objects with this static ability have a triggered ability that triggers “when you do” printed in the same paragraph. These abilities are linked. (See rule 607.2g.)
