The optimal use case for this card is repeatedly healing a strong or Voltron-esque ally. Obvious candidates include Spectrum (who becomes formidable if paid for with a wild resource), Iron Man (who can gain Aerial via Sky Cycle), Captain Marvel (who has big numbers), and Snowguard (who has 3 THW in Aerial form). From the recipient's perspective (the Voltron), we're essentially looking at a cost of 3 ER for an Aerial ally plus 1 ER for Wingman to heal 1 health per turn in perpetuity. This beats First Aid after 4 rounds, or Med Team after 6 rounds, although it imposes the restrictions that the recipient and donor must both be Aerial. Overall, it is a reasonably high-value card, but notably slow due to the 4 ER initial investment. This also adds another level of uncertainty and complexity to the deck's engine, as it requires both a donor and recipient to be in play before any value can be reaped.

As @Lennalf said, the best usagement is to employ a cheap AERIAL to negate cons damage of a big/voltroned AERIAL ally. Does it worth? If you ask me, having a 3-4 statline ally to attack or thwart for free every turn can be paid by itself very fast. The difficulty is to have it all happening in the right moment: a cheap AERIAL already in play for then Wingman appears; and a big ally to make use of all that.
In that regard, suit up solves the timing problem. Just, its an alter-ego event card.
