I'm not sure about the fan, I'd rather test it. White flag being OP as a permanent would depend on the change these cards bring to the meta.
I think white flag would be better as a spell (I said that in the thread already).
Thematically I'd have made the unstable runes a spell too.
Requip and Scrapyard seem fine and make a lot of sense as perms (both because of theme and dynamics).
I'm not sure if the current version of the generator is overnerf'd. I misunderstood it the first time too.
