A phenomenal little workhorse card for most of the X-Men, especially since most of them tick the dual boxes of wanting to periodically flip down to Alter-Ego and wanting their Identity cards back. The X-Mansion bonus of card draw is the icing on the cake so that this card replaces itself, and that is an easy condition to meet in a decent number of solo decks and incredibly common in multiplayer X-Men games where you're already likely coordinating those archetype Supports so that SOMEBODY has the X-Mansion. It's open-ended in what cards it can rescue, from resources like Molecular Acceleration to clutch events like Steel Fist, or any number of vital Supports/Upgrades that got killed off to the discard pile by an unlucky draw.
I wouldn't call it a mandatory staple, but it's a very easy sell to include considering that recursion is typically pretty great when it's this cheap and simple. It's imprecise in that you have to wait to see the cards on a future draw, which is a knock against it, but as games drag on and your board state is increasingly set this is exactly what you want to see to fill your thinning deck with your most important tools again for high-value turns. I won't always run three copies, but if I have spare space for it I'll always keep it in mind.
