This is the ultimate sideboard card for a deck playing Glittering Wishes, and therefore NOT strictly worse than Regrowth, which is not retrievable with Glittering Wish. All the same, don't let it lull you into a false sense of security. Your graveyard is still vulnerable, and it's still an extra 2 for that second copy, so think twice before only leaving yourself one Qasali Pridemage on that sideboard.

It's so perfect for this one purpose, you'd think it was made with that in mind.
5/5 for this reason alone.
