TAG

I have heard good things about Flesh and Blood TCG. From what I understand, the story behind it is similar to Pathfinder: a WotC partner got pissed at WotCs shenanigans and decided to make their own game.

There are also a ton of great non-collectible deck construction games. Unfortunately, they tend to fail fairly quickly because it is not profitable for local stores to host events. If you want a Magic-like one, I recommend Epic Card Game. It has a free-to-start app for Android, iOS, PC and possibly Mac.

I have come across a couple digital CCGs. Not sure if they are any good.

Also, sorry to be a “well actually” guy, but Pokemon TCG was always designed by The Pokemon Company. WotC just licensed the rights to translate the game.
