Ironclad Graveknight

When Ironclad Graveknight enters the battlefield,
put target Equipment card in a graveyard onto
the battlefield under your control and attach it to Ironclad Graveknight.
Whenever a creature dies, you gain control of all equipment attached to that creature and attach
them to Ironclad Graveknight.
A skeleton can hold just as much steel as it used to
hold flesh.
