When dazzling finds a unit, can it be played anywhere or only to your base/a battlefield you control?

Ruling: When dazzling finds a unit, it follows the same restrictions as playing any card - you can play it to your base or a battlefield you control unless the unit card itself specifies otherwise.

Nuances:

• Some units like Sneaky Deckhand or Deadbloom Predator have text that allows them to be played to different locations, overriding the default restriction
