One ruling from Wizards of the Coast
- 5 October 2018You may choose the same creature as a target multiple times since Bounty of Might says “target creature” multiple times. You may give three different creatures +3/+3 each, one creature +6/+6 and another creature +3/+3, or a single creature +9/+9.
