Exterminator Magmarch

Whenever you cast an instant or sorcery spell that targets only a single nonland permanent an opponent controls, if another opponent controls one or more nonland permanents that spell could target, choose one of those permanents. Copy that spell. The copy targets the chosen permanent.
{1}{B}: Regenerate Exterminator Magmarch.

Modern Horizons 3 Commander

Exterminator Magmarch's first ability won't trigger if no other opponent controls any nonland permanents that spell could target. If the ability does trigger but no other opponent controls any nonland permanents the spell could target by the time the ability resolves, the ability won't do anything.

If a spell has multiple targets but all of them are the same nonland permanent an opponent controls, Exterminator Magmarch's ability will trigger as long as another opponent controls one or more nonland permanents that spell could target. The copy will target only the chosen permanent and no other permanents.

If the spell that's copied has an X whose value was determined as it was cast, the copy has the same value of X.

If the spell that's copied is modal (that is, it says "Choose one —" or the like), the copy will have the same modes. You can't choose different ones.

The controller of a copy can't choose to pay any additional costs for the copy. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too. For example, if the spell you copy was kicked, the copies will also be kicked.

The copy is created even if the spell that caused the ability to trigger has been countered by the time the ability resolves. The copy resolves before the original spell.

The copy that Exterminator Magmarch's ability creates is created on the stack, so it's not "cast." Other abilities that trigger when a player casts a spell won't trigger.
