I didn't obtain it. As far as I know, no one in direct contact with me got it either.
My analysis of the HOME image they tweeted: the moves were egg moves, and the Clefairy didn't have fateful encounter, and levels shown were not set, the Encryption constant wasn't 0 (Characteristic was Mischievous, which cannot happen for 0 EC)
This roots out HOME event (EC wasn't 0) nor redeemed wonder card (no fateful encounter).
I presently believe the event was merely an in-game evolved Cleffa, hence why it has egg moves (as opposed to event moves), and why the levels were inconsistent, instead of being redeemed from a wonder card. (they can set no ribbons on wonder card, which the event can then be wonder traded)
edit: It also didn't look like Wild Clefairy, which had the egg moves passed to them via the new mechanic.
The levels don't look like Wild Clefairy levels, tho they could have simply leveled them a bit when transferring the moves over.
