Water Energy

Water Energy from the HS Trainer Kit is the priciest card in that 29-card set at 25.2% of the entire set's value of £50.42, which tells you how scarce or sought-after it's become. There's been no UK stock or graded sales in the last month, so the £12.69 price sits at the 30-day high with only Cardmarket as a reference point—the low was £8.46 just recently, so there's been real movement on this one.
