When playing Deadbloom Predator to an occupied battlefield, can other units from your base enter the same combat?

Ruling: No, Deadbloom Predator goes into combat alone when played to an occupied battlefield. Other units cannot accompany it.

Nuances:

• Deadbloom Predator is being played, not moved, so the normal rules for moving units into combat don't apply
• It's similar to playing a unit to your base or controlled battlefield, but with the ability to be played into an enemy-controlled location
