Is it haram to play Lorcana?

I have been getting into this trading card game called Lorcana. It is made by Disney. I was talking about it vaguely with my mom and she told me that I should not play it anymore or teach it to my brother. She told me that it could lead to gambling, is a waste of time, and forbidden in Islam. I do not play the game to win anything or bet anything. I simply play the game because I grew up watching Disney and enjoy the simplicity of the game.

Is it haram? If so, I feel I would have to quit it and give my cards away.
