Theorycraft. Based on an earlier deck I built where I accidentally milled myself when I played Roll the Bones. Realistically, you probably won't draw more than 3-5 cards by playing Roll the Bones with this version. Here is what I'm thinking:

• Use Kingsbane to kill large minions
• Use your minions to kill smaller minions and synergize deathrattle effects (try to cheat cheap copies of expensive minions out on the board, try to build up your Kingsbane by cloning Squidface)
• Use Sonya + Cursed Castaway combo to deal up to 10 damage per turn in whatever way you see fit, keep the board clean

A few thoughts on the strategy:

• Save Roll the Bones until turn 7, when you're hopefully also holding Dorian
• Play Dorian first, after which Roll the Bones should hopefully summon a few annoying minions on board (like Sylvanas, Mechanical Whelp, Southsea Squidface (you do have your Kingsbane equipped, right?))
• Play Sonya and sacrifice your 1-1s that Dorian generated, enjoy the deathrattle benefits, play the 1-1s you can again (hopefully your hand won't be too full)
• If you play Umbra the turn before Dorian and she doesn't get killed, the threats you create will be even more annoying

Kingsbane:

• Kingsbane is a Deathrattle card, and should also be picked up by Roll the Bones
• Sharpsword Tinkerer's Oil is a Combo card, and the only Combo card in the deck, so it should be picked up by Cursed Castaway
• Build up your Kingsbane by cheating out copies of Southsea Squidface via Dorian, Sonya, and Gang Up
• Since Roll the Bones will thin out your deck quickly, you should hopefully stumble into Leeching Poison sooner rather than later

Removal:

• Onyx Spellstones (should be buffed up from deathrattle minions)
• Kingsbane (single large target removal, when buffed)
• Sonya + Cursed Castaway (using 1-mana 1-1 version of Cursed Castaway and Sonya's power, you should be able to distribute up to 10 damage per turn in whatever way you see fit)
