It's dependent on unit cost, not soldiers. Get rid of all the cards you have in your attack units, 1, 2 and 3. Then put low unit cost cards in your unit. I'm not sure how useful it'd be collecting event treasure though, I've only used this method for activating the slots in the daily event last week and mainly dueled in the tablet collection.
