[2018] Lucio oh's cereal: Will it include a free toy inside?

There will not be a toy, but you will be granted a Loot Boost!

What is a Loot Boost?

A Loot Boost will grant you an additional standard Overwatch Loot Box the next three times you level up in-game. More details will be revealed here once this kicks off December 3rd.

You’ll just have to wait and see!
