I have been having a lot of fun and success with this deck, got me from diamond 3 to diamond 1.
Basically, play lots of minions and sacrifice them to your bloodrite kalis. Sometimes this is enough to win as you can get 10/10 or higher kalis. If your kalis is destroyed, use smugglers stash to bring it back with some pals and play it again. It will keep the stats from the last sacrifice so each time you bring it back it gets bigger and bigger.
Cards like combust and madness are used to deal with opponents threats, dont forget you can sacrfice the creature you steal from madness with any of your sacrifice cards (Kalis, devour, combust). Other Cards to Consider: Scheme
: Adds more consistency for drawing your Kalis and Stashes, a little expensive for the power cost though.
: Very powerful card if you can get it to hit, one problem is it has 2 shadow requirement so the powerbase would need to be drastically changed. Another problem is it is the only creature worth killing in the deck, so most opponents will be saving their removal the whole game and it is very rare that this guy hits.
-3 Memory Dredger, -1 Scheme, +4 Talir's Favored, powerbase changed. Memory dredger was getting removed too often as it was the only creature worth removing in the deck so oppoents would be sitting on all their removal cards. There was also a lot of clunky power hands where all the lands would come into play depleted, so with memory dredger gone we can now afford to run a lot more time sigils (Dredger was the only double shadow requirement card).
-2 Scheme, -2 Talir's Favored, +4 Torrent of Spiders, -2 Time Sigil, +2 Stonescar Banner. Thanks to Amph3's discovery, Torrent of Spiders is actually nuts in this deck, often generating 3+ units that are great blockers. Cut 2 favored and changed the powerbase a bit to be a little less heavy on time to more consistently get that Fire/Shadow requirment met.
