One of my favourite bits of design in the whole game, for several reasons.
It's a strong, efficient economy card. Best-case, it gives you net 7 credits for 2 clicks - nearly as strong as a double hedge fund, and from a lower base as well.
It balances out that strength with several interesting drawbacks. Most obviously, it's becomes rapidly less efficient if you have less than 6 cards in hand before you play it. There is also the possibility that you'll have more, agenda points in hand than you're comfortable showing the runner, leaving you both flooded and poor. The double click is a bigger ask for the corp than for the runner, and makes this a problematic turn one play.
Most interesting is the question of playing it with traps like Snare and Shock in hand. On the one hand, you miss out on the runner possibly faceplanting HQ with a fatal Legwork. On the other, showing off your spiky hand wards off runs on the agenda points you hold in HQ or might hold later. There's also the possibility of revealing your use of an unorthodox trap such as Edge of World. For a corp which thrives on confusion, giving away info is a real cost. Celebrity Gift is a good example of the influence system at work - the card gets played where its use is most involved and interesting, not where it is strongest.
Coming out of Genesis cycle, Jinteki sometimes felt a mass of gimmicks and tricks with nothing tying their use together. You had all manner of convoluted kill conditions, but lacked the money or defenses to pressure a wary runner into triggering them - weak ice was particularly harmful at a point where siphon abuse was its most rampant. This card, an actual efficient source of money, and Himitsu-Bako, a small, handy etr ice, marked a sea change for Jinteki, where the trickery started to get supported with solid cards.
It has an adorable giraffe on the art. Nothing seals a CCG card as a fan favourite like furry little critters of doom. If the thematic justification for the effect, where Jinteki's publicity stunts give away their schemes, is a bit of a stretch, it's still quite clever. The card always makes me smile when I hold it in hand.
Gift isn't as common as it was outside of CI these days, but it still stands up as a lovely card on its own merits, and worth thinking about for most Jinteki decks.
