Hey! Thanks for checking the game out! Sorry for the confusion and lack of explanation in the GUI, I'll try to clarify:
How do you customize character classes?
At the "selection screen" (two decks present in the middle):
- right click on the different lane class labels (eg. right click "Cleric") which will allow you to set specific classes for each lane
- right click on the left middle deck to set a 4 class preset for the left side
- right click on the right middle deck to set a 4 class preset for the right side
Once you have dealt the deck, you can't change classes until you bring up that screen again by winning/losing or clicking the restart button at the bottom menu bar.
And what are the different class abilities?
*I've added notes in the game's description
If you hover over the icons below the character name, some tooltip text will appear so you can see the different class abilities/restrictions.
If any moves don't match up with the "move assist", it's probably a bug.
If it's relevant, I couldn't figure out how to use any of the buttons in the menu bar in the bottom middle.

Good point about your spoiler! I was noticing that as well while I was testing but didn't take enough note of it. I think I could fix it by doing a card draw for that lane first, that way the second card is dropped instead... or I might just redesign some stuff in general...
I kind of just implemented as much functionality/classes as I could for this jam, and tried to leave enough customization open for the player to experiment with it.
Hope that helps explain the game rules/functionality better!
