I also have experience the Playmaker as card getter. Some SA's do not seem helpful. I won't train another Playmaker!
But FK and Penalty seem to work (sometimes)
The SA's I really like are Defensive Wall and Corner Kicker


The problem with SA's is you lose all the cones to the SA's when training him, and then have to catch up it terms of Q so I only train them very rarely now, and on a super fast trainer that their attributes fit with the SA, the ones born with SA's the skill set doesn't always fit, like a DC with FK, and so the skill is pretty useless unless you add to his attacking attributes..
