This is a bug with the way spells with 'Spree' are being resolved. When multiple additional modes are selected, and at least one of the selected modes become invalid (target is dead, for example) while the spell is on the stack, ALL selected modes fail to resolve. This is not intended as the ruling for 'Spree' states that: If at least one target is still legal, the spell will resolve but will have no effect on any illegal targets.

Steps to reproduce:
- Cast 'Getaway Glamer', selecting both modes.
- For the mode to exile a target non-token creature, target a creature
- For the mode to destroy a target creature with the highest power, target any other creature with the highest power
- Have the opponent kill the creature selected by the first mode with an instant spell, such as 'Shoot the Sheriff', while 'Getaway Glamer' is on the stack
- The second mode of 'Getaway Glamer' does not take effect i.e., the creature selected with the highest power targeted does not get destroyed
