Greninja

The cheapest copy has been sitting unsold at £2.00 for 8 days, so undercutting it won't help you shift stock. The trend is all over the place—55 UK sellers asking between £2.00 and higher, with the Cardmarket price at £10.25, which is nowhere near the asks; price to what's actually selling. This jumped 32.8% in a week on an 11.8% monthly trend, so either sell now or be prepared for a pullback. If you've got a Near Mint copy, that's your edge—57% of UK listings are played condition, which means clean copies are the scarce ones here.
