Today Shadowverse got released on Steam, is free to play and also has the Japanese language/voice/subtitles option, therefore I will be challenging myself by playing it on japanese (and hopefully managing to at least get trough the tutorial :S)
I'm not paid by them to say this, but from what I'm seeying looks better than expected , image below of my setup (game on left, Zkanji dictionary on the right)
The text is easily readable, all the text is voiced and it only goes forward when you click, so you can take your time to translate, great practice, and both tools are free so... if looks like your thing, give it a try ;)
