Amped Raptor
From Modern Horizons 3
First strike
When Amped Raptor enters the battlefield, you get 
(two energy counters). Then if you cast it from your hand, exile cards from the top of your library until you exile a nonland card. You may cast that card by paying an amount of equal to its mana value rather than paying its mana cost.
