Miami Marlins trade scenario that would Supercharge the lineup

The Miami Marlins are again without Jazz Chisholm and so therefore are again without any really threatening part of the lineup. We are more than halfway through the season and if you double each players total for the second half of the season only Jorge Soler will have a significant amount of home runs and they will have no single player with over 100 RBI.  

That can all change if they made a move that could be enticing with the currently visiting St. Louis Cardinals, who need to rebalance their roster.   The Cardinals have an abundance of young hitters and position players, yet they lack consistent pitching.  The Cardinals could either do a simple trade with the Marlins or a multiplayer trade if the terms are amenable.  The other wildcard when it comes to a potential trade with the Cardinals is Skip Schumacher knows the players and team and if he really goes for someone and encourages Kim Ng to make a trade for one or two players, then his advice should be taken. If he encourages and Kim Ng can't get the deal done and the players go somewhere else and shine, who do you blame?
