Official rulings
Two official rulings apply to Breaching Leviathan, newest first.
- The triggered ability affects all nonblue creatures, including those you control.
- The triggered ability tracks the creatures, but not their controllers. If any of the creatures changes controllers before its original controller’s next untap step has come around, that creature won’t untap during its new controller’s next untap step.
