To be honest, I'm not a fan of Absol in Lucario simply because there are better starters out there. Relicanth CL, for example, lets you put one card from your hand and into the Lost Zone, and if you do, you draw three cards. While Relicanth doesn't have a Poke Body nor does Relicanth do damage, it can put Pokemon into the Lost Zone more easily (one Energy >>>> two Energy) and provides drawpower early in the game.
