Greninja & Zoroark GX

The cheapest copy has been sat unsold for 7 days at £25.00, so undercutting it should move stock first. That listing is flagged as Lightly Played, and since raw copies are actually shifting at a median of £38.50 (27 sales in 90 days, about twice a week), a clean Near Mint copy can ask considerably more than the current low—the market median sits at £54.50. Don't bother grading: PSA 10 hasn't sold in two weeks, and the jump from a 9 to a 10 is steep at 3.3×, so only grade if the copy is truly flawless.
