Mega Lucario EX has become the card everyone seems to be talking about in Pulsing Aura, and yeah, the hype makes sense. It doesn't just hit hard; it punishes anyone who gives you a turn or two to breathe. If you're still piecing the list together, it's worth checking ways to buy cheap Pokemon TCG Pocket Items so you can finish the core faster and actually test the deck properly. Once Lucario gets rolling, the damage jumps from “pretty good” to “that's a knockout” in a hurry.
The cards you really want first
The starting point is simple: two Riolu and two Mega Lucario EX. I wouldn't cut either. You also want two Korrina, because that extra damage into EX Pokemon is one of the main reasons the deck feels unfair. Arena of Antiquity matters too, though I'm fine with one copy if space is tight. For the rest, I like one regular Lucario and a Hitmontop. Hitmontop gives you something useful to do early, especially when your hand is awkward. Then fill the list with the usual helpers: Poke Ball, Professor's Research, Copy Cat, and a Cyrus. Lucky Ice Pop, Pokemon Centre Lady, and Rocky Helmet all buy time, which this deck badly needs.
How Mega Lucario EX actually wins games
Mega Lucario EX is a Stage 1 Fighting-type with 190 HP, so it isn't paper-thin, but don't pretend it's safe forever. If it goes down, your opponent takes three points. That changes how you play. Fighting Pulse starts at 90 damage for two Fighting Energy. Add a third Energy and it jumps by 50, putting the attack at 140 before any outside help. That number is the real base line. From there, Korrina adds 30 against EX Pokemon, and Arena of Antiquity adds another 20. Suddenly you're taking huge prizes with one clean swing.
Timing matters more than it looks
The biggest mistake I see is people rushing the stadium onto the board. Don't do that unless you're ready to attack or you know your opponent can't replace it. Hold it in hand, set up Riolu, evolve when you can, and attach calmly. If you open Hitmontop, use it to soften targets while you build. If you open Riolu, don't panic, but be careful with your healing cards. Sometimes one Pokemon Centre Lady buys the exact turn you need. Korrina should also be saved for the knockout turn when possible. It feels tempting to play everything early, but this deck rewards patience.
Bad matchups and smart upgrades
Psychic decks are the rough ones. Mega Gardevoir EX and Mega Altaria EX can turn your weakness into a very short game, so you need to race them or force awkward exchanges with Cyrus and bench pressure. If you're missing parts, Hitmonchan EX, Sabrina, or Serena can fill gaps, but the clean version is still better.
