MTG Salvation

Here's hoping for a City of Solitude effect in set. Teferi, Time Raveler would accomplish the same thing but what would be the point in blue deck?

Grixis Fires of Invention with sideboard Teferi, Time Raveler.

The Jeskai Fires list splashing black with Fabled Passage for Kenrith maybe could make use of this. It's essentially draw 5 for 5 if you can protect T3feri, and the drawback is greatly reduced in Fires mirrors while the enchantment is on your opponent's board.

But not getting the best card in the 6 is still really painful, even if your opponent doesn't cast it.

fairly crappy card.
Even forgetting the ability that your opponent can cast this it is way worse than a draw 5 for 5 as losing the best card out of the 6 really hurts. Something like Tidings is just better for most decks.
Then taking in your opponent can cast the spell for free it becomes quite crap.

Only potential I see here is some sort of critical mass combo deck that would want this mostly for the combo turn and doesn't run spells they can give the opponent they would care about, only sorcery speed interaction for example.
