Perfected Strike

Perfected Strike is a 2-Energy Ironclad attack that deals 6 damage plus 2 more for every card in your deck with "Strike" in the name (3 more per card when upgraded). This includes Strike, Twin Strike, Pommel Strike, Sword Boomerang, and Wild Strike — any card with "Strike" in the title. With five starting Strikes, Perfected Strike already deals 16 damage (6 + 5x2), and it keeps growing with each additional Strike-named card in your deck.

Building around Perfected Strike means resisting the urge to remove your starter Strikes and instead augmenting them with additional Strike-named cards. In a deck with 8-10 such cards, upgraded Perfected Strike deals 30-36 damage for 2 Energy, which is extraordinary. The archetype is somewhat restrictive — keeping Strikes sacrifices deck quality elsewhere — but the payoff in a dedicated build is very real.
