While the release of Monster Crown [Steam] may be a while away, this monster catching and breeding game is confirmed for Linux.
Speaking to the developer on their Steam forum, they said this in reply to my question about Linux support:
Absolutely it will! I'm a huge linux fan myself!
I'm quite a big Pokemon fan and honestly, this actually looks like it comes somewhat close while still very much having its own identity.
