If Blitzcrank is played with Temporary (from Last Stand), does Temporary sacrifice it before Blitzcrank's Hold ability returns it to hand?

Ruling: Yes, Temporary sacrifices Blitzcrank before Hold can return it to hand.

Sequence:

• Begin of turn step happens (Temporary triggers and sacrifices the unit)
• Hold step happens (but Blitzcrank is already gone)

Nuances:

• The reminder text for Temporary explicitly confirms this timing
