In 2v2 Team Format, can an opponent use Charm or Dragon's Rage to move my unit to my teammate's battlefield, and what happens if they try?

Ruling: No, it is illegal to move a unit to a teammate's battlefield for any reason. Teammates can never have units at the same battlefield.

Nuances:

• A maximum of two players can have units at a battlefield, and those players must be opponents
• This restriction makes a teammate's battlefield an illegal destination for movement effects like Charm or Dragon's Rage
