The cheapest copy has been sitting unsold for 9 days at £8.59, so undercutting it should get you a sale first. That underseller is flagged as LP condition though, so if you've got a clean copy you can ask more—half the UK stock is played anyway, and Near Mint copies are thin on the ground. The card's been up 25.4% this week and 39.6% this month on genuine momentum; it hit £11.81 in the last month against a low of £8.46, yet most asks still cluster around £13.23, leaving the cheapest listing 35% underwater.
