I love the wild card and I love the Tigers. I think the Tigers win in 5.
The wild card has allowed an awesome, yes awesome, Cardinals team fight it out and get their postseason ace back in time to truly contend. Likewise, it made everyone jitter while Philly almost stormed back from a season beset by injuries. Meanwhile, a team like the Nats shut down their ace and were not the same team. So, it opens the door for teams that can have a say. I've felt all year that St. Louis is a much better team than their record, and their run differential is really good, so credit to them for advancing. They won't beat the Tigers this time, but if they do good for them.
