Liliana is good post board because you can make them sacrifice a Progenitus if they managed to get through your removal, e.g. fetched a Dryad Arbor to feed to Natural Order. The most problematic creatures of theirs are Heritage Druid and Wirewood Symbionte, but once you kill them, Elves suddenly get left behind. Summa summarum, as long as you prioritize your targets, are not afraid to lose some extra life in the process (let them beat you with some less relevant creatures in order to deal with the more threatening ones that may soon appear on the battlefield) and have some relevant cards in your sideboard, you should be fine.
