Right now, if I have a card that, for example, draws and ramps, I add the #ramp and #draw tags to it. The card then appears in the “draw” AND in the “ramp” categories.
Personally, I tend to prefer cards that fulfill multiple roles. So when I build a deck, I would want to have the ability to quickly identify cards that only fulfill 1 role, so I can get rid of them. But with the current visualization, this is difficult to do.
So personally, I would prefer a new kind of visualization, where if I have a card with the #draw and the #ramp tags, it shows up in a separate category called either “ramp + draw” or “draw + ramp”. That way, if I look at the cards in the “draw” category, that category ONLY includes cards that I am likely to cut, and that would be really useful for me.
