This is great, but it feels like it's missing such an obvious 'Training Arena' where I can choose my hand and practice the various combos, and a way to skip to the start of my turn. The villains take a long time and I can't see my cards until they gotten at least partway into it, and it sucks when I'm using someone for the first time and have to wait for the set-up, only to screw up on the card I should've picked.
