To be clear, what I intend to say here is as follows:
The issue here was a host-side issue in allowing in a power the hosts didn’t understand, and an opponent-side issue in others ignoring the power because they didn’t understand it (it would’ve been way less effective if people threatened Ash early on, or watched their energy spending to avoid these kinda issues). Those are supposed to be the lines of defence against “submit something super OP and nobody else understands it” - as a host, you should not just let in a power you don’t understand
Claiming it was “unsporting” or whatever to submit a complicated power, or that everybody should just try not to submit complicated powers, when there were these explicit lines of defence against this kind of strategy which failed feels like… it removes a large big of strategy and fun for people who like complicated things
