I’ve been meaning to set up a simple way to prototype basic decks on my tablet or phone. The most basic version takes an array of text elements and cycles through each on demand, and at the end of the array it shuffles and starts again.
I’m not proficient in Javascript but I can tinker with basic code. I was able to cobble together something based on this code snippet by Paul S on StackOverflow. You can test out my Zombie Plague deck here.
