So i was the person asking for better Command the dreadhorde UI. Here is what i meant.
[[Command the dreadhorde]] is pretty taxing card. We are operating in 2 different zones. We need to pay close attention to our life total as well as what we already has chosen. Meanwhile, Arena doesn't make it easy. Life total is covered. We don't know what we picked from other GY. We don't know how much damage we will take currenty (ofc player count in head, but mistakes happen). The spell also autoresolves once all possible targets are chosen without confirmation.
So here is what card should do if given attention. Show current life total. Show current cumulative CMC of chosen cards. Show already picked cards on the bottom of the screen like during casting [[Planewide Celebration]] with different outlines indicating owner. Demand confirmation if total damage would exceed current life total of the caster.
EDIT: Hey, my first Sliver Medal! Thank you!
Thanks for clarifying. Those are good suggestions, and we'll see what we can do.
