Does Rek'Sai allow units played from zones other than hand (like champion zone, banishment, or hidden) to have Accelerate?

Ruling: Rek'Sai grants Accelerate to any friendly unit played from anywhere other than your hand, including the champion zone, banishment, and hidden zones.

Nuances:

• Works with chosen champions from the champion zone
• Works with cards played from banishment (like Aurora's flip or Nocturne)
• Works with hidden units
• Works with blink spells, token generation, and resurrection effects
• Can be used in non-red decks in 2v2 or with effects that play units from non-hand zones
• The champion zone is explicitly not part of the hand, which is why hide/hidden needed clarification in v1.1 to specify it could hide from champion zone
