By the way, in case you don't already know this, in Expert stages (and any other times ones), you can go ahead and make a move even if it doesn't make a match, unlike in the regular stages. You can take advantage of this to try setting up a 5 Pokemon match to have the highest chance of activating an ability.This also means that it's possible to keep a combo going for the whole stage, if you're good enough. So if you trigger Pummel, Pyre, etc., you can go ahead and do the whole stage with a damage bonus if you keep that combo going.
Yeah, I read about that. I only attempted Absol and Lucario a few times so far, and failed to catch them.
