Can I still get him from the cash shop to battle? I cannot find him Thanks

Those gemstone challengers are only available for one month out of the year, unless it's during a special sale like Black Friday when they bring back most cash shop items.

The topaz one is available in November. If you want it sooner, you will likely have to buy from a user if you can find one for sale.

Thanks so much for explaining. I hope it comes back this November Judy
