If Yi's controller has 2 units in a battlefield and one dies during showdown (via Void Seeker), does the surviving unit get Yi's +2 bonus?

Ruling: Yes, the surviving unit gets the +2 bonus from Yi. Yi is a passive ability that is either on or off, and once the unit dies, it switches on.

Sequence:

• Showdown begins with 2 units present (Yi's ability is off)
• Void Seeker kills one unit during showdown
• Yi's passive ability switches on
• The surviving unit receives +2
