Can you use Sett's effect to recall a unit into your base if the targeted unit is already in the base?

Ruling: Yes, you can use Sett's effect to recall a unit into your base even if that unit is already in the base.

Nuances:

• Sett, The Boss doesn't target - it's a replacement effect and replacement effects cannot target
• You simply have the choice of replacing any unit death if that unit has a buff on it
