When Lee Sin is buffed with Last Stand (giving Temporary) and saved from Temporary's kill trigger by Zhonya's Hourglass, does Lee Sin keep the Temporary keyword and his buffs when returned to base?

Ruling: Yes, Lee Sin keeps both the Temporary keyword and his buffs when Zhonya's saves him and returns him to base. Zhonya's only prevents damage/death, it does not remove keywords or buffs.

Sequence:

• Last Stand gives Lee Sin Temporary keyword and doubles his might
• At end of turn, Temporary triggers and attempts to kill Lee Sin
• Zhonya's Hourglass saves Lee Sin from death and sends him to base
• Lee Sin returns to base with all buffs and the Temporary keyword still active
• On the next opponent's turn, Temporary will trigger again and kill Lee Sin (unless saved again)

Nuances:

• Zhonya's does not remove the "Give it Temporary" effect from Last Stand, only prevents the death
• This extends Lee Sin's survival by one turn, but he will die to Temporary on the following turn
