Can Amateur Recital send Baron Nashor to base?

Ruling: No, Amateur Recital cannot move Baron Nashor to its base because Baron Nashor has protection from being chosen by enemy spells and abilities.

Sequence:

• Amateur Recital's ability states "you may move a unit at a battlefield to its base"
• This requires the player to select which specific unit to move
• When an ability requires selecting a specific game object, the word "choose" is implicit even if not explicitly written
• Baron Nashor's ability "I can't be chosen by enemy spells and abilities" prevents it from being selected
• Therefore Baron Nashor is an illegal target for Amateur Recital's ability

Nuances:

• The key distinction is that abilities requiring player selection of specific objects count as "choosing" even when the word "choose" doesn't appear in the card text
• This differs from abilities that automatically or programmatically identify targets without player selection
