I always love Sylvanas due to her interactions with other cards. Play Dead, Feign Death, Spiritsinger Umbra, Void Terror, and Reincarnate all are excellent combos with Sylv. As mentioned, Rag has the Silver Vanguard synergy which I'm a huge fan of in wild (many good targets like Kel'Thuzad, Sneed's Old Shredder and The Lich King) so it's a pretty cool card to have as well. Justicar is just a beast with armor warriors and probably the #1 craft if that's what you're focusing on.

At the moment I cant recommend Justicar in Controll Warrior, Scourgelord Garrosh is just stronger. 

i'm the one that's also sayng for the particular case of CW Justicar>Sylvannas> rag rag is just too slow and unreliable with the amount of sticky  token board decks that exist in wild, while Justicar gives you a lot of survability and Sylvannas gives you a threat that you can technically replace with any other threat

Wait, what year is it?

WHAT did you say? How in the world is Scourgelord Garrosh stronger than the fatigue queen herself Justicar Trueheart.

Scourgelord Garrosh?  Its debatable if its even a good card. 

Wild Control Warrior without Justicar Trueheart is like swimming in an empty pool.

What do you mean with craft for free

Also: i do have Frost Lich Jaina , and i do want a wild elemental mage ( i have the cards).

i do know that Sylv i a gud idea to craft, but im still not sure. I dont have many ways to use her right now
