Not much on its own. It trades at $0.20 with the cheapest listing at $0.01, which is bulk pricing: shipping a single copy costs more than the card.

Buying the single. It is $0.20, below the $6.71 a Journey Together booster pack costs, with no chance of pulling something else.

61 of 190 priced printings, with 60 printings in the set worth more. The top one is Lillie's Clefairy ex at $103.56.

No. The single is $0.20 and a sealed booster box is $245.25, so the card is 1226x cheaper than buying a box to chase it.
