Nice! I've added EX Jaina and EX Midori, and since the online version uses "EX Name" when referring to them, I've changed Grave's EX version to follow the same convention.
Yeah, that seems like it would be hard... Still, I have confidence that you can find a solution!
It's a race! Can I finish putting in all the EX characters fast enough to make adding this feature unnecessary?
This is a bit inconvenient, but hardly the end of the world. Fairly low priority, I should think, considering that people will primarily use this for the normal characters anyway.
One thing I noticed is that the list of which cards are attacks, throws, blocks and dodges needs to include the Destiny cards for EX characters. As it is right now, the only way to tell that Midori has gained a new rank of card is to look at the ability list.
