Ankh runes.

You are correct about how ankh runes work. It does indeed stop me from

using malloran, as well as my opponent, if I just let it sit there. However,

I'm a bit more clever then that, so when I use ankh runes, I can still

make use of malloran, but my opponent can't. I find thise quite useful.

As for diffusion, why not use a pyramid rune as well if you're worried

about being summoned?
