Minzel Scrollspark

When Minzel Scrollspark enters the battlefield or
attacks, you may target one instant or sorcery of
converted mana cost 2 or less in your graveyard
and cast it without paying its mana cost.
If you do, exile it at end of turn.
"It's elementary, my dear Rina. I turn our foes into
ash and our problems are solved. Any questions?"
"Yeah Minzel...exactly which element?"
