Can Charm move any unit, even if they are rested or on another battlefield, and what are the limitations?

Ruling: Charm can move any enemy unit to any legal location on the board, ignoring ganking restrictions and regardless of whether the unit is rested. The only limitation is that units cannot be moved into an opponent's base.

Sequence:

• Charm uses "move" rather than "standard move", which bypasses normal movement restrictions
• The unit can be moved between battlefields without ganking
• The unit can be moved even if rested
• If moved into contested territory, it will start a showdown

Nuances:

• Charm only targets enemy units, not your own units
• Units still cannot be moved into another player's base (illegal placement)
• Ganking restrictions only apply to "standard move" actions, not to "move" effects in general
• The Golden Rule applies: when a card contradicts normal rules, the card takes precedence
