Can you flash a unit from Vilemaw Lair to base?

Ruling: No, Vilemaw Lair prevents any units from moving from it to base, whether through card effects or standard moves.

Nuances:

• Units can only leave Vilemaw Lair by moving to another battlefield (via ganking or card effects) or through recall effects (mostly via cards that specify recall)
• The restriction applies to all movement types, including flash effects
