Seven Dwarves My original plan for Throne of Eldraine was that we'd have exactly seven Dwarves in the set
One, it made it clear who you could and couldn't use the enchantment on, and two, it allowed you to use a Flight effect (something that grants a creature flying) to break them free from the enchantment (if the creature gains flying, the aura falls off as it can only enchant a creature without flying)
At worst, this card acts as an optional Phyrexian Arena, as long as you have a creature to target with it, which is already good enough for the format
Many of your dorks are small utility dorks or smaller flying dorks both of which do a lot more for you when slightly bigger
Its certainly not a play pattern that interests me, but there are a fair number of folks who enjoy it, so I figured its worth mentioning
