I am keeping my roster down to say, my best 30 or so. Which does include some rotation as things come along. I have a few shards in waiting for 2x. A few ancients, voids, and a yellow. All of those are likely to be poor, odds-wise. I just do not have the champs and the silver to do much with, so it is what it is.
With the L50's I cashed in, along with some chickens, I have a L60 Monster and L60 Cillian, those are my main roster changes. But everything I have is light on something, speed, acc, def, hp, etc so slowly working around all the bends to see how much I can gain, wherever. Those artifacts cost a fortune in silver, takes a while to get through L14 - 16.
I have some 6* artifacts for Kael, slowly working those up the ranks. I have found after restarting this game a few times that having too many champs is really counter-productive, for me at least.
Now that I have Monster I am better able to stay in Silver 4, so I have been getting a few medals for the GH, but that has been pretty tough.
Still only have 5 legos in development, and not the name brand ones. Waiting on SCYL, that will be nice to have again.
