Accidental Necromancer

Whenever a Skeleton you control would die,
exile it instead. Return it to the battlefield at the
beginning of your next end step.
Magecraft - Whenever you cast or copy an instant
or sorcery spell for the second time each turn,
return target creature from any graveyard to the
battlefield tapped under your control. It's a black
Skeleton in addition to its other types..
