Whatever his next capture is should star instead imho. As long as Fletchinder and Pikachu don't have that honor, idc.
Why not Fletchinder, just out of curiosity? It's got a good deal of battles so far, but nothing super-noteworthy since besting Talonflame. I mean, its wins against Machoke and Jumpluff were still good, but I don't see why it shouldn't star against Valerie. It depends on Ash's sixth too, if it's Phantump then I'd say wait and have it star against Olympia with Hawlucha, but if it's Honedge or even Bergmite, then maybe give it the chance to star against Valerie.
