I really just can't think deep into this. The disbelief hits me whenever I imagine all the logistics for spell card rules to work in Gensokyo. Those little details are very difficult to rationalize.
Like, shit, this is clearly the "first" version of the rules. Only random crits are perfectly fair and balanced. Nothing else is. What if somebody finds a way to cheese the current system? They'll have to spread new rules like that again. And new rules sets a precedent implying that the current rules might not be perfect. People will start using homebrew rules then.
And then there's the matter that beauty is subjective. I, for one, think glorious melee combat is beautiful. But if the people of Gensokyo don't think so, am I breaking the spirit of the spell card duels then?
I really applaud Azmaya showing her take on this, most certainly inspiring other people (including me) to shimmy in and think about their own interpretation of the spell card rules.
