My first thoughts on the Pikachu ex SAR were a little negative since it seemed a tad plain for a card billed to be the chase of the set, but I dunno, it’s got a wistfulness to it which is a little charming. It might not beat Vivid Voltage Chonkachu at its peak interest, but this one might have...
Cool to see a new artist, it seems they are also an official artist for BanG Dream! which is a franchise based around idols/seiyuus, so fitting they do the Lisia SAR. I agree it's unfortunate that the card is thematically similar to the SR.
One of the better looking full arts and kind of a throwback to the BW/XY era style, but this also kind of goes to show that as much as we can appreciate those old SRs now, they aren't enough to carry a modern set.
