Mew VMAX

This Mew VMAX is priced at £22.99 on a set that's only two weeks old, so expect the market to soften over the next few months—Japanese cards typically drop for the first three after release. That said, early demand can be volatile, so if you're sitting on stock, watch the listing prices on the major platforms rather than panic-shifting into the first dip.
