How it works
Activate Lithatog's first ability by sacrificing Sword of the Meek.
Skittering Precursor triggers, creating a 0/1 Eldrazi Spawn creature token.
When the Eldrazi Spawn enters the battlefield as a 1/1 due to Jetmir, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Eldrazi Spawn.
Resolve the Lithatog ability, giving it +1/+1 until end of turn.
Activate the Eldrazi Spawn by sacrificing it, adding C.
