Can someone please explain how you can place M.Sarinda without both her and another hero dying? I played a demonologist and then her, both died. I tried another stiched and her, both died. Death toll seems to suggest that when you play her, another of your heroes will die (and only that hero), but what exact type of hero does that need to be and why do both keep dying when it doesnt seem to suggest that 2 dying from her placement is even possible...
There are two abilities working here: Split Hero: If this unit is deployed in a full faction battlegroup it is destroyed. Death Toll: When this champion is deployed the closest real champion you own is destroyed. So I guess you were trying to use her in a Full Faction deck (which means she dies on deploy), and the Death Toll also kills the nearest champion. She is designed to be used pretty much exclusively in a stitched deck (a split theme), where the ability to kill your own champs can be really useful.
