What is you that you like about this game?
There's a grip of other games out there. What is it that you like about Warhammer AoS Champions that hooked you? What keeps you playing?
For me, there are two primary factors. One is the fact that I can play online with the same cards I have IRL - that's a HUGE selling point for me. The other is the tactical aspect of the lanes. You see that a little bit in Elder Scrolls: Legends, but I don't recall seeing that much of any place else.
