Each of Lucario EX‘s attacks requires one more Fighting Energy than the previous attack. This allows for an easy progression through his different attacks, making him quite the formidable force right from Turn One.
His first attack, Missile Jab deals 30 damage, and ignores Resistance. This is important as there are a good number of Pokemon in the card game that do have Fighting Resistances. The second attack, Corkscrew Smash, not only deals 60 damage, but allows you to refresh your hand until you have 6 cards in hand. This sort of card advantage on such a damaging attack is quite formidable.
His third and final attack is Somersault Kick for 3 Fighting Energy, which deals 100 damage. It’s a fitting final attack to deal a crippling blow to a likely already weakened enemy. While it doesn’t offer anything special beyond that, 100 damage for only 3 energy with no drawback is a fairly strong attack.
While his dedication to Fighting Energy makes him not as “splash-able” as some other EX cards, his pure power level makes him a formidable weapon and a great EX to build a deck around. Lucario is also one of the most popular Pokemon around, making him both a sought after collectible as well as a powerful card for deck-building.
