Forum:Facedown targets

When card effects require a tribute for a specific name of monster; lets say for example a "ninja" (doesn't state "face-up"), can a face-down ninja monster be a correct target for ninjutsu art of duplication??

does this apply as well with a face-down iswarm/evilswarm monster targeted by infestation terminus? --119.92.123.171 (talk) 03:45, April 19, 2013 (UTC)
