Possibly the X-23 upgrade you want to get to the table soonest.

To be fair, X-23 has a significant number of ways to heal. And -at best- this card will stave off one or two flips down.

But that's still a pretty huge benefit.

This is a card that appears to live in the aggregate, with its maximum benefit being achieved by an early pay. But that's inaccurate.

This is a card that provides immediate benefit, no matter when it is played. Particularly when you are playing a Honey Badgerrecursive deck. This card will eventually pay massive dividends, so long as you recognize that and get it into play.
