Can you use Dragon's Rage to move an enemy unit to a battlefield where their teammate is already present?

Ruling: No, you cannot use Dragon's Rage to move an enemy unit to a battlefield where their teammate is already present. Teammates cannot both occupy the same battlefield, and no more than two people can have units at a battlefield. The target would need to be rechosen because it would result in an illegal gamestate.

Nuances:

• Even if one unit would die as a result of Dragon's Rage, the move still cannot go through because the unit needs to be able to legally 'land' at the location when it moves
• Dragon's Rage does two things (damage and movement), and both must be legal
• The same restriction applies to other movement effects like Charm
