I usually play slower, control decks, so racing the face is usually not doable. That said you can always try teching (and hope you draw decently and they don't highroll you). It's Wild after all, so you have more options that can fit your deck.
Sylvanas Windrunner is just a strong card on it's own and you can fit it almost anywhere.
Druid: Poison Seeds
Hunter: deathrattle synergies with Sylvanas (or even Spider Bomb helps) such as Play Dead, Terrorscale Stalker and Nine Lives (since you can search her faster with stuff like Tracking, Stitched Tracker or Master's Call)
Paladin: ? stuff like Equality helps, but usually isn't enough
Warrior: ? I find Control Warrior to be a weak Wild archetype currently
