the problem is that it only affects you and this creature, which is why its at the very bottom
Like most Pokmon cards, the value of Darkrai depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (DP Black Star Promos)
It reads, When Stalking Yeti comes into play, if its in play, it deals damage equal to its power to target creature an opponent controls and that creature deals damage equal to its power to Stalking Yeti. Once again, we have a seemingly redundant line that flows rather metaphysical
Yeah it leaves a token lying around, but when you're playing in a format with giant dragons and menacing Eldrazi, giving your enemies a 3/3 beast seems like a suitable trade off
The rest of the set also has a few coveted cards, with Mew VMax being a meta threat in its prime and Espeon VMax having some of the most beautiful Eeveelution art ever printed
With solid utility in Psychic decks and a pull rate as rare as a well-timed Future Sight, the card ticks all the boxes: nostalgic appeal for Gen II fans, competitive relevance for tournament-goers, and scarcity that keeps market prices on a steady incline
