Just don't play it.
I was wholly disappointed by this theme, but I thought at least I should make a point. "Spellcasting" to me is pretty much equivalent to "Bullshitting". It's so dumb even as a fantasy. How one can be so lazy and disrespectful to human intellect? I'm disgusted and feel dirty even to talk about this. The only thing that you could do is to mock it, but even that took a lot of energy from me (because I hate being negative). The whole experience was just meh, but I'll just leave it here for future reference. It's sad that some people actually thought that this was a good theme.
I have not laughed this hard in a while! Too bad humor is not a rating category.
Sure, I too have been disappointed by the theme of many a jam before. Usually I grit my teeth and force myself to come up with something even tangentially related with ok results, if I dare to say so myself. Other times I've simply used a combination of some of the other top themes and paid lip service to the actual theme, no-one stopped me and very few cared!
So, ah… If you hate being negative then simply cheat a little to gain happiness!
(I'll abstain from ratings this time, it would not be sporty of me!)
