Fighting and Steel types
If you look at the cards, the 1st is a FIGHTING type and so it has Psychic weakness.
The other Lucario's card is a steel type, meaning it resists to Psychic.
Also the 2nd card, you can see is weakness is fire, so it means the Lucario in the card is a steel-type.
In real game, Lucario has normal damage to psychic-moves and is weak to fire-moves.
Also if you check here (down the page), all Lucario cards are fighting-type and only 1 is steel-type.
Hope this helps.
