Tons of Energy in the right situation, which I do find comes up with some regularity, but a nothing-card the rest of the time. Don't over index on speculative Energy gain early in the run, but be ready to Expect a Fight if you're offered this card in a run with decent card draw and Attack Card density.
Extremely powerful with card draw effects, especially Aggression or Pillage. Get a bunch of attacks in hand, then play this and dump them all! Also works nice with Thrumming Hatchet from the colorless pool.
Draw 2 cards. At the start of your turn, Exhaust the top card of your Draw Pile.
Gain 8 Block. Gain another 8 Block if you have Exhausted a card this turn.
Gain for each Attack in your Hand. You cannot gain additional this turn.
Deal 10 damage. If Fatal, raise your Max HP by 3. Exhaust.
