i recently came across a lightsworn deck. to shut down a dark type deck he sided shadow imprisoning mirror. he also ran necro gardna. now a common misplay with this combo (if you ever come across it) is to banish necro gardna while shadow imprisoning is active. however, this cannot be done. it is like going to a store with no money. necro gardna is a graveyard effect and it get negated by shadow imprisoning
