Sceptile

The cheapest copy has been sat unsold for 7 days at £6.52, so undercutting it will move your stock first. That said, this card's jumped 25.4% in a week with only 24.5% growth over the month, so you might want to sell into the spike or sit tight for a pullback. The £6.52 listing is flagged as MP condition anyway — a clean copy can ask considerably more given that all 5 UK listings are played copies, making Near Mint the genuinely scarce version here.
