Dire Fleet Daredevil

Oracle Text
First strike
When Dire Fleet Daredevil enters the battlefield, exile target instant or sorcery card from an opponent's graveyard. You may cast that card this turn, and you may spend mana as though it were mana of any type to cast that spell. If that card would be put into a graveyard this turn, exile it instead.
Card Rulings
1/19/2018 The effect of Dire Fleet Daredevil doesn’t change when you can cast the exiled card. For example, if you exile a sorcery card, you can cast it only during your main phase when the stack is empty.
1/19/2018 Casting an exiled card causes it to leave exile. You can’t cast it multiple times.
While this card is someone less consistent and can't be used to counter something out of the blue, the ability to steal someone's Thoughtseize, Path to Exile, Fatal Push, Abrupt Decay, etc. could make this card fairly hilarious in modern.
While this card could theoretically "whiff", there aren't too many decks out there that lack a good target for this spell (Even tron might give you Ancient Stirrings).
Think of it as CMC: X1R
-Card Advantage
-First Strike
Remember Eternal Witness doubling a Fatal Push for 4 mana? This just did it for 3, and it has first strike. So what if its opponent. It's good.
God forbid someone flickers a deck with it.
