Manalink 2016/08/27: Eldritch Moon v2, duel

What exactly should be the correct behavior/interaction ?

-

Finally after a lot of effort fixed both and other bugs in commit 4c872af.
The prevention damage will happen only as a shield as I couldn't make it work manalink way, so I expect AI to need a lot of help with this which I haven't done.
