So one of my players showed up with a Kobold Rogue with a Deer familiar (Find Familiar from magic initiate).
Checking the verbiage on Find Familiar I notice any beast with a 0 CR is usable.
So he is using it as a controlled mount with a 50 foot move (100 feet with dash) which is immune to AOOs. Also since he is mounted he gets sneak attack on any enemy within 5 feet as long as he does not have disadvantage.
I love that he found this combo.
