Xbow 3.0 still viable??

Getting back into the game for the first time in a few years, it’s not the same game I played AT ALL. Evolutions, weird spinny boxes, different tower people??? And so many new cards. The last time I played was when champions first came out. The last time I consistently played was when they added a new max level for cards. So trophy road has a new ranked system and stuff where cards are maxed out at level 12. Is Xbox still viable for climbing ladder?? Or do I need to find a new deck :(
