One ruling from Wizards of the Coast
- 1 October 2008You may choose just the first mode (targeting a creature with flying), just the second mode (targeting a creature without flying), or both modes (targeting a creature with flying and a creature without flying). You can’t choose a mode unless there’s a legal target for it.
