Fixed Possessed Portal since you cant discard a card unless you have one permanent to sacrifice, replace 0/0 with donothing

Moved Maralen of the Mornsong to borderline since the effect is not draw replacement but players cant draw anything (there isn't any stated "would draw"), maybe we can have CANTDRAW ability in the future.
