Shadowverse

When I started playing, I completely agreed with Koshi's opinion, and I didn't understand this idea of "we know you like Albert (Hamsa/Jeanne/etc.), so we put him on your card backs so you can play as Albert while playing as Albert." Later, I got used to it, and now I play with some card backs that have pictures, but I still prefer the basic ones. But honestly, the card backs in Heroes are cooler, though.
